STM8S/STM8L TSSOP20 Programming Socket & Test Burn Adapter
STM8S/STM8L TSSOP20 Programming Socket & Test Burn Adapter
STM8S/STM8L TSSOP20 Programming & Test Socket with Power Indicator Light
Take your embedded development workflow to the next level with this professional-grade STM8S/STM8L TSSOP20 Programming Socket. Designed for engineers, hobbyists, and electronics developers, this burn socket makes programming and testing STM8 series microcontrollers fast, reliable, and repeatable — no soldering required.
Why Choose This Programming Socket?
Built around a premium imported gold-plated chip socket, this board delivers stable, low-resistance contact every time. The gold-plated contacts resist oxidation and ensure consistent signal integrity across hundreds of programming cycles.
Key Features
- Wide Compatibility: Supports the vast majority of STM8L and STM8S series chips in TSSOP20 packaging with a 0.65mm pin pitch
- SWIM Interface: Program and test your chips directly through the industry-standard SWIM interface for seamless integration with ST-LINK programmers
- 4-Digit DIP Switch: Easily select between STM8S and STM8L chip families with a dedicated onboard 4-digit DIP switch — no jumper wires needed
- Power Indicator Light: Onboard LED power indicator provides instant visual confirmation that the socket is powered and ready
- User-Replaceable Crystal Oscillator: Swap out the crystal oscillator freely to match your target application frequency
- Full I/O Breakout: All I/O pins are broken out via 2.54mm double-row headers for easy breadboard or circuit integration
- Compact Form Factor: Dimensions of just 50mm × 44mm keep your workbench tidy and make the socket easy to integrate into test fixtures

Frequently Asked Questions
Q: What STM8 chips are compatible with this TSSOP20 programming socket?
A: This programming socket is compatible with the vast majority of STM8L and STM8S series microcontrollers that come in TSSOP20 packaging with a 0.65mm pin pitch. The onboard 4-digit DIP switch allows you to select between STM8S and STM8L configurations quickly and accurately.
Q: Do I need a separate programmer to use this burn socket?
A: Yes. This socket connects to your programmer (such as an ST-LINK) via the SWIM interface. The socket itself is a test and programming adapter — it holds the chip securely in place and routes all connections, while your external programmer handles the actual firmware download.
Q: Can I use this socket for both programming and functional testing?
A: Absolutely. The socket supports both programming (burning firmware) and functional testing operations. All I/O pins are broken out via 2.54mm double-row headers, allowing you to connect external circuits or test points while the chip is seated in the socket.
Q: Is the crystal oscillator included, and can I replace it?
A: A crystal oscillator is included on the board, and it is designed to be freely swapped by the user. This flexibility lets you match the oscillator frequency to your specific target application without requiring any board-level modifications.
