STM8S103F3P6 -01- Blink test

Some cheap STM8S103F3P6 Breakout Boards recently came in my mailbox from China / AliExpress and i decided that it was time to test them.

This is my first experience STM boards so i did the simple Bink test.

First i heated up my soldering iron to added some Dupont pins to 2 of this boards. At the bottom of this blogpost you see more pictures of the soldered pins  

For programming a SWIM interface /  ST Link is needed. Luckily some weeks earlier a simple ST Link arrived. This was a simple PCB with an USB port and the following connections

To protect the PCB i heat-shrinked this ST Link connector.

Bottom  [SWD]	Top [SWIM]
3V3	RST
SWD0	GND
SWCLK	SWIM
GND	5V

With Dupont wires I made the following hardware connections between the programmer and the STM8S103F3P6 Breakout Board 

STM8S103F3P6	Programmer
3V3	3V3
SWIM	SWIM
GND	GND
NRST	RST

After configuring the Arduino IDE so that it can handle STM8  i successfully tested the board with the Blink program from the Arduino IDE (1.8.10) with the settings below.

STM8S103F3P6 Breakout Board with Dupont pins

On one breakout board i used male ( and male pins with an angle) Dupont pins as often seen with this modules.
For the other STM8S103F3P6 breakout board i used the long Dupont pins with male and female connectors. For the SWIM interface  used male Dupont pins. I also added connectors to the + and - . The idea is that it can be easy placed in a project and the female headers still give easy access to all pins.
It is possible to use both variants on a breadboard.
