      bpi:bit board is 5 cm x 5 cm in size, weighs 10 ~ 12 grams, it houses a 20-Pin edge connector, built-in lighting matrix with 25 programmable full-color LEDs , two photosensitive light sensors, two programmable buttons, an NTC resistor, a buzzer and a nine shaft sensor (triaxial acceleration Three-axis gyroscope and three-axis magnetic compass), 

      the I/O space configuration is as follows:

      • Full color LED matrix: GPIO4 
      • Photosensitive sensor: GPIO36 (Analog A0, upper left), GPIO39 (Analog A3, upper right) 
      • Button switch : GPIO35 (Botton A), GPIO27 (Botton B) 
      • Temperature sensor: GPIO34 (Analog A6) 
      • Buzzer: GPIO25
      • MPU-9250 9-axis sensor: GPIO0, GPIO21(SDA), GPIO22(SCL)

      Hardware

      Hardware description

      Webduino Bit is the latest board of Webduino with much more sensors on top of its basic functions(Wi-Fi connection, muti-connectivity,multi-board...). It uses ESP32 module,one of the most efficient and stable chipset in the market, which has built-in 2.4G Wi-Fi and Bluetooth,448KB ROM,520KB SRAM,speed up to 600 DMIPS,and 40 nm technology.

      Webduion bit board has a compact size of 50mm x 50mm, weighs 10-12 grams.It has 20 pins at the bottom,25 full color LED array in the middle, two photo cells,two buttons, one thermistor,one buzzer,one 9-axis sensor(3-axis accelerometer,3-axis gyroscope and 3-axis magnetometer)

      PIN definitions

      The edge interface is much compatible with those of micro:bit. so you may able to use micro:bit accessories on bpi:bit

      MPU9250 9-axis sensor

      The 9-axis sensor, MPU9250, is placed on the BPI:bit board. and MPU9250 uses I2C 0x69 address.

      The 9-axis is the combination of 3 separate triple axis sensors. For more detailed information of this chip, click here MPU 9250 datasheet to view the datasheet.

      BPI:bit power

      When you use BPI:bit, you need to supply the board first, and the bit supports three power supply modes

      • 1.micro USB port:USB cable power supply, the design of BPI:bit board has Micro USB interface, which is quite common in daily life and is quite convenient to use.
      • 2.Battery port:Through 2 pin battery power supply socket, can through the lithium battery, battery pack to power supply board, interface fool proof design, don't worry about the power supply through the 2 pin battery power supply socket, can through the lithium battery, battery pack to power supply board, interface fool proof design, don't have to worry about power supply meet the problem.
      • 3.Goldfinger :Power is supplied through the gold finger, and the gold finger at the bottom of the board contains the power interface. Meanwhile, it has both input and output functions and has high compatibility.
