Power usage on the WeMOS Lolin32 D1 & Lolin32 Lite boards. I've had a "Lolin32 Mini D1" arrive in the post today. Just tested deep sleep, and it is 125uA - that is about a couple of years on 3xAA 2500mAh batteries. The "Lolin32 Lite" I tested a few weeks ago was 890uA - which is only about four months in deep sleep on similar batteries. I recently purchased some Lolin/Wemos S2 Mini boards (the ESP32 successor to the popular Wemos D1 Mini that uses the ESP8266). Whereas there were hardly any changes required for programming and uploading to the D1 Minis, there were several additional steps for uploading sketches to the S2 Mini. Namely you have to hold the 0 button down and then press the RST button to put the board into a Step 4: MicroPython Installation. First, Wemos has a serial/USB chip based on CH304G. This is the same chip found in cheap Arduino-clones and you must install a proper driver for Mac or PC. Follow the instructions on this site to install the driver. Step 3: Setting Up the Power Strip. Make sure the power strip is UNPLUGGED! Unscrew all the screws at the back of your power strip. Generally power-strips comes with tamper-proof screws, so you need a screw-driver designed to unscrew the tamper-proof screws. Take off the top cover and examine the circuitry. .
