ESP32-S2-MINI-1 is a powerful, generic WiFi-MCU module that has a rich set of peripherals. It can be applied in a wide variety of scenarios relating to wearable electronics, smart home, etc.
The module embeds ESP32-S2FH4 chip, an Xtensa® 32-bit LX7 CPU that operates at up to 240 MHz, and features a PCB antenna.
The chip has a low-power co-processor that can be used instead of the CPU to save power while performing tasks that do not require much computing power, such as monitoring peripherals state change or whether an analog value exceeds the threshold.

Jargon buster
Plain-language definitions for the technical terms used above.
- 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.
- 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.
- RTC
- A Real-Time Clock keeps track of time even when the main processor is asleep or powered down, usually with a small backup battery. It matters for data logging and tracking projects that need accurate timestamps.
- 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.
- SRAM
- Fast temporary memory used by a processor while a program is running. More SRAM helps with projects that handle larger data buffers, networking, displays, or more complex code.
