ESP-14 is an ESP8266 with an attached STM8003F3P6 in a package very similar to an ESP-12 module. Elliot used the ESP-14 for two reasons:
- the ESP-14 has more ADC inputs than the ESP-12
- a powerful ESP8266 bundled with a minimal STM8S running Forth is a crazy thing waiting to be done!
The schematics around the ESP-14 looks like this:
The ESP8266 connects the tiny STM8S003F3P6 to a Linux machine using JeeLab’s esp-link.
The ASCIIcinema recording of a remote log-in via WiFi to an 8bit Forth, with a demo of interactive testing on the Forth console is well worth watching!
Check out Elliot's article, it's great!
PS: Elliot and me discussed other use cases for the ESP-14, like battery powered IoT devices. All the tools to make this happen are now available!
