#72648 Thanks for the info. Got some new ESP-01S and discovered that for my purpose, the original ESP-01 works a little bit better! Specifically, I use deep-sleep mode on these, which means I have to run a jumper from the ESP8266 chip pin 8 (GPIO16) to RST; the ESP-01S have a resistor and a cap right at the corner of the chip making it hard to get into and attach a jumper wire. Also, the ESP-01 that doesn't have a power LED means I don't need to remove the power LED :). I usually do replace the 4Mbit serial flash with an 32Mbit while I'm at 8Mbit is usually sufficient but the W25Q32FVSSIG are pretty cheap.
