Description

A base for the ESP32-C3 OLED with screw terminals, for wire that has to stay put. The board plugs into the two black sockets in the middle, each of its sixteen holes comes out to its own terminal, and a LiPo connector, charger and power switch are built in.

Highlights

Screw terminals. Two blocks of eight 3.5 mm ways, one down each side.
Battery power. JST PH 2.0 connector, TP4054 charger and a slide switch. Plug in USB with the switch ON and a cell connected to charge it.
Battery monitor. An open solder jumper connects a divider across the cell to GPIO 2, so a sketch can read its own battery level.
Two 4.8 mm mounting holes, 16 mm apart.

Appriciate the quality and service from Lonely Binary. Second time purchasing from them and wont be the last. As a beginner in electronics world, their website has helped me a lot. Not many places you can find the required information, explanation and the materials you need at one spot. Keep up the good work lads.

I started by emailing the company wasking for the standalone screw terminal boards for the ESP32-C3 . I really hope you start stocking them stateside, but thank you for shipping them so quickly and listing them on your site as well.
