Banana Pi Bit board with EPS32 for STEAM education
Thank you for your support ! Please note : Taiwan customer please contact local website to buy
Epacket logistics is expected to be 15-30 working days,and slow update of logistics informations, If you mind ,please choose the fast logistics channel . Thank you : )
The BPI:bit (also referred to as BPI-bit, stylised as webduino:bit) is an ESP32 with Xtensa 32bit LX6 dual-core processor based embedded system. support Webduino, , MicroPython as well as Scratch X programming environments.
BPI:Bit development board 5 cm width 5 cm long, weighs about 10 ~ 12 grams, in addition to below 20 Pin goldfinger interface, a built-in a 25 full-color LED lighting matrix, two photosensitive resistance button switch a temperature sensing resistor A buzzer and a nine shaft sensor (triaxial acceleration Three-axis gyroscope and three-axis magnetic compass), space configuration is as follows:
- Full color LED matrix :4
- photosensitive sensor :36 (A0 left) 39 (A3 right upper)
- button switch :35 (A) 27 (B)
- temperature sensor :34 (A6)
- buzzer: 25
- 9 axis sensor mpu-9250:21,22.
BPI Bit : provides a wide range of onboard resources, supports photosensitive sensor, digital triaxial sensor, digital compass, temperature sensor interface, gold finger interface and micro:bit fully compatible.
Webduino:bit have 25 intelligent control LED light source that the control circuit and RGB chip are integrated in a package of 5050 components.Cascading port transmission signal by single line.Each pixel of the three primary color can achieve 256 brightness display, completed 16777216 color full color display, and scan frequency not less than 400Hz/s.
