-This board hasn't been fully documented yet. Please make a pull request adding more info to this file.
+This development board includes a Bluetooth Low Energy-enabled ISP1807 from Insight SiP (based on the nRF52840) and six sensors: acceleration, magnetism, gyro, temperature, humidity and air pressure.
 
-The description should be written to inform a CircuitPython user what makes the board unique and link to relevant info about it.
+The development board is programmed with a bootloader. You can use the Arduino IDE or Circuit Python to develop your program. It has two switches and two LEDs each that can be used programmatically, and it also has a piezoelectric speaker.
+
+It features a TPS63030 high-efficiency step-up/down converter and runs on CR2025 or CR2032 coin cell batteries. The board outline is the same as the Raspberry Pi Zero, so it can be used in a Raspberry Pi Zero case.
