SPIDER Automation ACEBOTT Micro:bit Shield V1.0 | Multifunctional Expansion Board | PWM, UART, SPI, I2C & 18650 Charging
Description
The SPIDER Automation ACEBOTT Micro:bit Shield V1.0 is a miniature multifunctional expansion board designed for the Micro:bit platform. It provides expanded pin access and peripheral connectivity through standard color-coded headers, making different pins easier to identify during wiring and system development.
The expansion board supports 3 PWM outputs, UART, SPI and I2C interfaces, providing connectivity options for compatible electronic peripherals and control systems. It also provides LED and button control functions, with P3–P10 used for LED control and P5/P11 assigned to A/B button control.
A built-in Micro-USB charging interface provides charging functionality for a compatible 18650 battery. When power is connected and the board is connected through Micro-USB, the battery can be charged. Two onboard charging indicators provide status information: CHRG indicates that the battery is charging, while STDBY indicates that the battery is fully charged.
The board supports a specified 3.7–5V input voltage and can be used with an 18650 battery for offline program operation. Its compact multifunctional configuration makes it suitable for robotics, electronic experiments, interactive devices, wearable applications and other Micro:bit-based development systems.
