Simple Pogo Programmer for ESP8266 Modules
https://hackaday.com/2019/12/07/simple-pogo-programmer-for-esp8266-modules/
ESP8266 development boards like the Wemos D1 Mini and NodeMCU are an excellent way to get a one-off project up and rolling quickly, but their size and relative complexity mean they aren’t necessarily a good choice for even short-run production hardware. On the other hand, programming the bare ESP modules …read more (https://hackaday.com/2019/12/07/simple-pogo-programmer-for-esp8266-modules/)
