A kick-ass microcontroller board with everything you need in a compact package that fits in your pocket. Integrated battery, power management system, Arm microcontroller, USB bootloader, 4 high-power PWM outputs, and 12 GPIOs.
Why? After years of wiring together portable LED controllers that all consisted of a lithum batter, charge controller, power switch, and an arduino nano (or similar), I wanted something better. I always found those versions to be janky and fragile -- not to mention concerned that damaging the pouch cell battery might make it explode! This board has everything I need with room to expand.
- 32-bit microcontroller with frequency up to 100Mhz (STM32F11xx)
- High-capacity 18650 lithium battery with integrated 500mA charger
- 4 high-current PWM outputs (2.3A per channel!) with an LED on each for debugging.
- Additional 12 GPIOs (USART, I2C, SPI, USB)
- USB bootloader
- Tactile on/off switch
- Tactile user button with built-in debounce circuit
- Breadboard friendly
- Supports Arduino & CircuitPython.
- Durable AF! (Put a tube of heat shrink around it for a super easy case if you'd like.)
