##Introduction The FireBeetle 2 ESP32-E (N16R2) IoT development board equipped with 16M Flash and 2M PSRAM. It is designed to provide superior performance for applications such as the LVGL graphics library for interface design and interaction. Built on the foundation of Espressif's ESP32-WROOM-32E-N16R2 module, it boasts a 32-bit dual-core processor with a clock frequency of up to 240MHz. With support for WiFi and Bluetooth dual-mode communication, it is an ideal choice for IoT scenarios.Abundant peripheral interfacesIncluding 17 digital pins, 11 analog pins, 3 UART interfaces, 1 SPI interface, 1 I2C interface, 1 I2S interface, and 2 DAC interfaces, it can meet various hardware connection needs.Board Overview of FireBeetle 2 ESP32-E (N16R2) Development BoardDual power supply modesSupporting both USB and external 3.7V lithium battery power supply, it can automatically switch between power sources under dual power supply, and supports both USB and external DC charging modes.Support for multiple programming methodsIncluding Arduino IDE, ESP-IDF, Micro-Python, etc., catering to different developers' programming habits.Compact design, convenient for embeddingWith a size of only 25.4mm × 60mm, onboard WiFi and Bluetooth antennas, and using stamp hole design, it is convenient to embed or integrate into PCB prototypes.The difference between ESP32-WROOM-32E and ESP32-WROOM-32UETheESP32-WROOM-32E (this product) uses an onboard PCB antenna. This type of antenna is realized through PCB technology, does not require separate antenna assembly, is not easily damaged by touch, and is convenient for whole machine assembly. Onboard antennas can save space, reduce costs, and because they can be carefully positioned on the board, they can provide signal integrity. However, their gain may be lower than that of external antennas.The ESP32-WROOM-32UE, on the other hand, connects to an external antenna via a connector. External antennas can be installed on the outside of the device and include both omnidirectional and directional antenna types. The main advantage of external antennas is that they can provide higher gain, thereby enhancing the communication range of Bluetooth or WiFi. Furthermore, this product is one of the low-power IoT development boards in the FireBeetle series. If it does not meet your requirements, you can refer to the FireBeetle Series Selection Guide to choose a more suitable model. ##Features Equipped with ESP32-WROOM-32E-N16R2 dual-core moduleClock frequency up to 240MHz, with 16M Flash and 2M PSRAM for large memory capacityLow-power development board, supporting dual-mode communication of WiFi and BluetoothOnboard GDI display interface for quick connection to display screensOnboard charging circuit and PH2.0 lithium battery interface, supporting dual power supply and automatic switchingSupports various programming methods such as Arduino IDE, ESP-IDF, Micro-PythonCompact design, small size, suitable for space-limited and embedded IoT projects ##Applications Home automation renovationRemote control of robotsEnvironmental data monitoringSmart lighting controlControl panel UI design ##Specification Power ParametersInput VoltageUSB-C interface: 5V DCPH2.0 interface: 3.7V Li-ionVCC pin: 5V DCMCU ParametersProcessor: Tensilica LX6 dual-core processor (one core for high-speed connectivity, one core for independent application development)Clock Frequency: 240MHzSRAM: 520KBROM: 448KBFlash: 16MBPSRAM: 2MBOn-chip Clock: 40MHz crystal oscillator, 32.768KHz crystal oscillatorWireless ParametersWi-Fi Standard: FCC/CE/TELEC/KCCWi-Fi Protocol: 802.11 b/g/n/d/e/i/k/r (802.11n, up to 150 Mbps), A-MPDU and A-MSDU aggregation, supports 0.4us protection intervalWi-Fi Frequency Range: 2.4~2.5 GHzBluetooth Protocol: Compliant with Bluetooth V4.2 BR/EDR and BLE standardsBluetooth Audio: CVSD and SBC audioBluetooth Frequency Range: 2.4~2.5GHzPeripheral ParametersDigital Pins × 17: IO0, IO1, IO2, IO3, IO4, IO12, IO13, IO14, IO15, IO17, IO18, IO19, IO21, IO22, IO23, IO25, IO26Analog Pins × 11: IO0, IO2, IO4, IO12, IO13, IO14, IO15, IO25, IO26, I34, I35UART Interfaces: ×3SPI Interface: ×1I2C Interface: ×1I2S Interface: ×1DAC Interface: ×2Touch Interfaces: ×7LED PWM Channels: ×16RGB_LED: WS2812Display Interface: GDIOther ParametersInterface Compatibility: FireBeetle V2 series compatibleModule Size: 25.4mm × 60mmWeight: 23.4g ##Documents Product wikiPinoutDimensionGetting Started (Use for the first time)Arduino Tutorials DatasheetSchematic2D FileSTP FileShell stl file ##ShippingList FireBeetle 2 ESP32-E (N16R2) IoT Microcontroller x118pin-2.54mm Pitch Pin x118pin-2.54mm Pitch Pin Female x114pin-2.54mm Pitch Pin x114pin-2.54mm Pitch Pin Female x1

Jargon buster

Plain-language definitions for the technical terms used above.

BLE: BLE stands for Bluetooth Low Energy, a Bluetooth mode designed for lower power use and modern phone compatibility. It matters because BLE support can make the module easier to use with Apple devices and battery-powered projects, though it may behave differently from classic serial Bluetooth.
DAC: A digital-to-analogue converter turns numbers from the microcontroller into a real analogue voltage. It matters if you want to generate simple waveforms, audio-style signals, or variable control voltages rather than just on/off outputs.
ESP-IDF: ESP-IDF is Espressif’s official software development framework for ESP32-family chips. It gives more direct control over the hardware than beginner-style environments, which can help with advanced features like Wi-Fi, Bluetooth, audio and power management.
ESP32: ESP32 is a family of microcontroller modules with built-in wireless features such as Bluetooth and WiFi. Knowing this product uses an ESP32-based module helps explain how it provides wireless serial communication and firmware update features.
I2C: I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
I2S: I2S is a digital audio interface used to send sound data between chips, such as from a microcontroller to an audio amplifier or DAC. It matters if your project needs cleaner digital audio output than a basic buzzer or PWM signal can provide.
IDE: Short for Integrated Development Environment, a program used to write, run and manage code. It matters because some learners prefer a traditional coding workspace instead of a guided notebook-style lesson.
IoT: Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
LVGL: LVGL is an open-source graphics library for building buttons, menus, gauges and other user interfaces on small embedded displays. Support for LVGL matters if you want to create a polished touchscreen interface without drawing every screen element from scratch.
microcontroller: A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
PCB: A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
PCB antenna: A PCB antenna is an antenna pattern built directly into the circuit board rather than a separate metal antenna. It matters because placement, nearby metal and enclosure design can affect wireless range.
PWM: Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
SPI: A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
UART: UART is a simple serial connection that sends data over separate transmit and receive wires, often labelled TX and RX. It matters because this module is designed to replace a wired UART cable with a wireless link while keeping the same serial data format.
