2 pcs. STM8 STM8S103F3P6 16MHz USB Development Board

We make it happen!! These STM32 boards are a very fast, and far more powerful alternative to Arduino development boards like the NANO, for example.

If you buy boards / modules like that from China, you will need some time, equipment, and experience to install the Arduino Boot Loader, and to make these modules compatible to the Arduino IDE. Connected to the Arduino IDE, these boards will not be recognized at all. They don’t even show up as USB device on your computer!

Our STM32 board is different!! It is compatible to the Arduino IDE, will be recognized as USB device, and can be easily programmed using the Arduino IDE and Arduino code. This is an exclusive offer from Universal-Solder.

Our STM32F103C8T6 USB Development Board “Blue Pill” 72MHz comes with the Arduino Boot Loader and the typical “Blink” sketch already installed.

This STM32 Mini USB Development Board for Arduino in about the size of an Arduino NANO is 5x as fast as a NANO or UNO, and comes with more ports, 4x higher A/D resolution, and 4 times higher PWM resolution. The 3.3V supply is generated on board, all you need is a 5V power supply for it (USB or auxiliary). Most of the ports can handle 3.3V and 5V as well (please see data sheet).

The STM32F103C8T6 micro controller contains a precisely internal RTC with its own 32kHz clock crystal, and an input for a backup battery (3V lithium for example) to power the timekeeper for many years also when the micro controller itself is sleeping or not even connected to a power source.

These are the quiet impressive features of that little module:

– 29 I/O ports, thereof 15 PWM out and 10 analog in
– Real Time Clock with crystal 32kHz and backup battery input
– 2 x I2C bus, 3 x serial interface (GPIO)
– only 53 x 22 mm small
– 72MHz internal clock speed for high processing power
– on board ST-Link header for in-circuit programming/debugging
– 3.3V device with 5V tolerant I/O ports (most of them)
– Micro USB port for programming and power supply option

Our STM32 module has 40 pins, and it fits in a DIP40 socket.

This module comes with the pin headers already assembled! It is more convenient for us to program and test the device with the headers already installed. We also offer a version without Arduino Boot Loader and with the pin headers not installed (but included in the package).

We are very sorry that Roger Clark closed his website STM32Duino.com, which was a cornucopia of information about running Arduino on STM8/32 modules, and our reference for information about setting up Arduino IDE to work with STM8/32 modules.

The information we still can recommend: STM32DUINO on GitHub (Examples, Arduino Core, Arduino IDE Bord Manager Files)
