Characteristic:
The ESP-01S WiFi module relies on ESP8266 chip, so ESP-01S has all of the features and efficiency of ESP8266.
Evaluating with former model ESP-01, ESP-01s has beneath benefits:
The PCB structure has modified for an enchancment in WiFi radio efficiency.
4MB Flash Reminiscence, upgraded from 512KB.
Newest model ESP-01s, with stronger sign
4MB Flash chip: XMC 0H32BHIG, XM25QH32CJIG or XM25QH32CHIGU10Q, vast chip or slender chip, ship by random.
