BPI-Bit Lite is an educational board that runs on Arduino, Webduino and MicroPython

Jul 31, 2022 — by Giorgio Mendoza 1,905 views

The Banana Pi BPI-Bit Lite is a development board following the BPI-Bit. This tiny device is powered by the ESP32-S3 from Espressif and it features Goldfingers I/O connectors.

The microprocessor found on this device is the Xtensa Single-Core 32-bit LX7 with maximum frequency of 240MHz.  Unlike the previous model, the BPI-Bit Lite includes 2048KB of PSRAM but it has less ROM (128KB) and RAM  (320KB).

Other notable differences are that the new model only supports Wi-Fi and there isn’t a 9-axis sensor as in the BPI:Bit. The BPI:Bit Lite has also replaced the old MicroUSB port with a USB Type-C.

 

The BPI-Bit Lite still provides two photosensitive sensors, one temperature sensor and a larger buzzer. The number of accessible Goldfinger IOs is still nineteen and there is support for ADC, LCD Camera, PWM, SPI, I2C, I2S, RMT, TWAI Controller, SD/MMC. The new model also provides twenty five 8-bit LEDs which are controlled by one GPIO output.
