DIY ESP8266-07 spider rig dev board and PSU
Posted: Fri Apr 03, 2015 7:28 amI've build a spider rig for my ESP8266-07 board.
Tripple and double male/female header rows and connections for power and separate 4 pins for the FTDI/Serial interface
Only thing that needs to be done is an extra 2 rows for the 3.3v and 5V rail in the bottom left corner.
All is placed on a single sided perfboard.
De PSU is build on 4 18650's that are chained in series.
An average of 16 volts powers two boards. One is a digital PSU and the other is a fixed buck converter. (5v and 3.3V out)
An extra display is added to monitor battery health
The entire PSU needed to be fixed on the back of an 18650 4 slot battery case. With the additions of some PCB connectors to attach wires, it became my personal mobile digital PSU.
