Sonoff S26 is a very good smart socket based on ESP8266, which can be easily reflashed with many existing pogo pin adapters. But this year (2021) a new version appeared: S26 R2 with a newer chip ESP8285. As a result, the PCB layout has changed and existing S26 software adapters are no longer suitable.
So, to enjoy runtime hackability with NodeMCU and lua on these new S26 R2s, I had to create a new pogo pin adapter to reflash them. Hopefully, it will also be suitable for reflashing devices with Tasmota firmware.
You will need four P75 pogo pins (17mm long, 1.02mm in diameter) to assemble the adapter. I have used P75 LM2.
