Overview

Image of a SEGGER STM8 Adapter, a small green circuit board with multiple gold pins. It features labels for "VCCT," "GND," and a website link. The design includes two terminal blocks and a connector for easy interface with other devices.

The STM8 Adapter converts the standard 20-pin 0.1" connector to the SWIM connector and a standard 10-pin connector. In addition the target board can be powered using the external input connector on the STM8 Adapter. The adapter is able to optionally power the connected target hardware. 3.3 V or 5 V supply voltage can be selected using a Jumper. The target is supplied via the VCCT connection when the supply option is jumpered.

Please note that this adapter is usable only for the purpose of flash programming. It cannot be used with a J-Link and it cannot be used for debugging STM8 devices.

Schematics

Schematic diagram of a programming interface showing connections for a probe, including pins like VTREF, TCK, RESET, and a voltage regulator (VREG) with outputs of 5V and 3.3V. It features a ground connection indicated by a green LED symbol.

The Flashers are tested with a 4 way ribbon cable of type ERNI part no. 839016 (100 mm) mounted with keyed header (female) mounted on both sides (resulting in a total length of around 120 mm).
