This module includes an integrated trace antenna, fits the IC to an FCC-approved footprint along with including decoupling and timing mechanisms that would need to be designed into a circuit using the bare nRF52840 IC. The Bluetooth transceiver included on the nRF52840 boasts a BT 5.1 stack and supports Bluetooth 5, Bluetooth mesh, IEEE 802.15.4 (Zigbee & Thread) and 2.4Ghz RF wireless protocols (including Nordic's proprietary RF protocol) allowing you to pick which option works best for your application.We've also routed two I2C buses, 2 SPI buses, eleven GPIO, dedicated digital, analog, PWM & PDM pins along with multiple serial UARTS to cover nearly all of your peripheral needs.MicroMod is a modular interface ecosystem that connects a microcontroller “processor board” to various “carrier board” peripherals. Utilizing the M.2 standard, the MicroMod standard is designed to easily swap out processors on the fly. Pair a specialized carrier board for the project you need with your choice of compatible processor!Get Started with the MicroMod nRF52840 Processor GuideFeatures:nRF52840 General Features: ARM Cortex-M4 CPU with floating point unit (FPU) 1MB internal Flash -- For all of your program, SoftDevice, and file-storage needs! 256kB internal RAM -- For your stack and heap storage. Integrated 2.4GHz radio with support for: Bluetooth Low Energy (BLE) -- With peripheral and/or central BLE device support Bluetooth 5 -- Mesh Bluetooth! ANT -- If you want to turn the device into a heart-rate or exercise monitor. Nordic's proprietary RF protocol -- If you want to communicate, securely, with other Nordic devices. Every I/O peripheral you could need USB -- Turn your nRF52840 into a USB mass-storage device, use a CDC (USB serial) interface, and more. This is a big add compared to the nRF52832! UART -- Serial interfaces with support for hardware flow-control if desired. I2C -- Everyone's favorite 2-wire bi-directional bus interface SPI -- If you prefer the 3+-wire serial interface Analog-to-digital converters (ADC) -- Eight pins on the nRF52840 Mini Breakout support analog inputs PWM -- Timer support on any pin means PWM support for driving LEDs or servo motors. Real-time clock (RTC) -- Keep close track of seconds and milliseconds, also supports timed deep-sleep features.
