Various breadboard-friendly boards based on ESP8266 or other chips are available on the market, but some readers are not quite satisfied with the offerings, and need more available pins on the breadboard so they ended up hacking the board matching their needs by either bending header pins, or soldering modules to stripboards. As I browsed new arrivals on ICstation website, I found a tiny board with ESP8266 module that exposes I/Os via what looks like 2.54 mm pitch header that should fit right into a breadboard.
But after further checking only three I/Os are exposed, and the board is actually specifically designed for wireless switches, and comes with firmware that works with eWelink app used in Sonoff devices. So the module could be useful for people wanting to control devices without doing programming at all, and limited to no soldering. Just connect the module, and control it without smartphone.
- PSA-B ESP8266 module supporting 802.11 n/g/n WiFi
- Ceramic antenna
- 6-pin header with 5V, 2x GND, OUT pin, LED pin, and key input pin.
- Misc – Status LED , matching button
- Dimensions – 2.7 x 2.5 x 0.8 mm

Without a big capacitor on the power line, there’s no way that board will be reliable.

What duplicate link? There’s no link at all. I just made that collection for this post, so it’s not like it’s been posted to cnx-software before. ???
