Banana Pie BPI:Bit STEAM Education Development Board

Banana Pi BPI:Bit (also known as BPI-bit) is a micro-development board designed for STEAM education, jointly developed by Banana Pi team and Webduino team. Its core positioning is to help youth and educators quickly realize creative programming and IoT project development through the combination of hardware and software, especially suitable for primary and secondary school creator education scenarios.

Hardware configuration

1.Main Control Chip
ESP32 dual-core processor, integrated 2.4GHz Wi-Fi and Bluetooth dual-mode communication, with low power consumption, high RF performance and stability.
The computing power reaches 600 DMIPS, built-in 448KB ROM and 520KB SRAM, supporting complex computing tasks.

2.Sensors and Peripherals
25 full-color LEDs: 5×5 matrix arrangement, single line cascade control, support 16.77 million colors display, scanning frequency ≥ 400Hz/s, suitable for dynamic lighting effects.
Dual photosensitive sensors: located in the upper left (GPIO36) and upper right (GPIO39) for ambient light detection.
Dual programmable buttons (GPIO35, GPIO27) and buzzer (GPIO25) to support interactive design.
Temperature sensor (GPIO34) and MPU-9250 nine-axis sensor (three-axis accelerometer, gyroscope, magnetometer), integrated motion and environment sensing function.

3. Interface and expandability
20 Goldfinger interfaces: Fully compatible with BBC Micro:bit, and can directly use Micro:bit expansion accessories (e.g. motor driver boards, sensor modules).
GPIO control: support I2C, SPI, UART and other protocols, can be connected to servo, OLED screen and other peripherals.
Power supply: support Micro USB, battery power (2-pin interface) and gold finger GPIO power supply, flexible to adapt to different scenarios.

4.Physical Characteristics
Size only 5cm x 5cm, weight about 12 grams, easy to carry and integrate into the project.
