This is a development board based on the STM32F103C8T6 processor with an on board 128x64 pixel Blue OLED display.
64KBytes Flash, 20KBytes SRAM, 72Mhz.
Why did you make it?
To avoid a birds nest of wires, I made this for convenience, to quickly plug in and test new programs.
What makes it special?
Having an on-board 128x64 OLED display with auto power on reset, a LiPo battery charger and a laser cut Acrylic frame for protection. A genuine STM32 processor, not a clone.
A USB mini B type connector is used rather than the more fragile micro USB.
The OLED display is connected by i2c on pins PB6 and PB7. The LiPo charger is preset to charge at 100mA. It is assumed the LiPo battery is over-discharge protected (as most small phone type batteries are). Battery connector is a standard 2-pin JST-PH type. The VBat pin has back flow diode protection to allow connection of a RTC battery if required.
Note: You can program this board with FTDI, STLINK or install a boot loader to allow programming through USB. You can use the Arduino IDE or STM32CUBE IDE and various others.
