+The SuperMini NRF52840 is Nice!Nano clone which in turn is based on the Pro Micro layout. This means that it can be used with almost any Pro Mcro keyboard. Unlike the Pro Micro however it sports wireless functionality in the form of Bluetooth and pins to use/charge a lithium-ion battery.
+
+The nRF52840 MCU uses an ARM Cortex-M4F CPU clocked at 64MHz and offers 1MB of flash memory and 256KB of RAM. Although CircuitPython will use up most of the flash memory.
+
+# Access bootloader
+To get to the bootloader whilst the board is connected short RST to GND twice within 0.5 seconds.
+
+# Purchase
+You can purchase this board from [ICBbuy on aliexpress](https://www.aliexpress.com/item/3256805833497363.html).

+Tiny, but mighty! This board with a powerful ESP32-S3 MCU measures in at 24.8mmx18mm (23.5mm for just the PCB, the USB-C connector sticks out a little bit). Despite it's small size it still exposes a wealth of GPIO connections - a whopping 34 in total. It does however have 'only' 4MB of Flash storage rather than the more typical 8MB found on most ESP32-S3 boards (and even 16MB on some).
+
+ * ESP32-S3FH4R2 dual-core Xtensa® 32-bit LX7 processor - up to 240MHz
+ * USB Type-C Port
+ * ME6217C33M5G low dropout LDO, 800mA (Max)
+ * WS2812 GRB LED (R and G are swapped from their usual order)
+ * BOOT button
+   Press it and then press the RESET button to enter download mode
+ * RESET button
+ * 34 GPIO contacts (18 available on breadboard friendly castelated edges, 16 on the bottom of the board through exposed pads)
+ * 2.4G ceramic antenna 
+   * Supports 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth® 5 (LE) 
+   *although CircuitPython at the time of writing does not offer proper Bluetooth supports for ESP32-S3 chips, a NRF52840 based board will serve you better in that regard*
+ * Built in 512KB of SRAM and 384KB ROM, onboard 4MB Flash memory and 2MB PSRAM
+ * Castellated module and onboard ceramic antenna, allows soldering direct to carrier boards
+ * Supports flexible clock, module power supply independent setting, and other controls to realize low power consumption in different scenarios
+ * Integrated with USB serial port full-speed controller, 34 × GPIO pins allows flexibly configuring pin functions
+   * 4 × SPI, 2 × I2C, 3 × UART, 2 × I2S, 2 × ADC, etc.
+
+*Due to the limited flash memory available on this board it hasn't been 'build' with esp-camera support - if that's something you want to use you'll have to roll your own build and sacrifice some other feature to make space (like the at the moment non-functional bluetooth)*

+
+*Warning: At the time of writing their product page does contain 2 small mistakes*
+It states it has a WS2812 RGB LED on pin 10. It does not.
+ 1. It's a GRB LED, not RGB. Keep this in mind when trying to use it.
+ 2. It's on IO21, not 10.
