Yet another ESP Dev Board Design
Posted: Mon Sep 19, 2016 9:54 amHey,
just want to share a little board design. It is build upon an ESP-12F and breaks out every pin except the reset and enable pin.
Features:
The LEDs are connected with a 4.7k resistor in series, which limits the current to about half a milliamp.
Each line of LEDs can be disabled by removing the little jumper.
The IOs connected buttons can be used as outputs but have strong pull-ups (1k), except IO16 which has none.
As I created this board to be milled by my little router, it is only single sided with widths and spacings of more than 10mil.
Below are some pictures of two finished boards.
Project is located here: (download gerber: open the board design and press fabrication output (top bar))

Hope someone finds it useful and thank you for this great forum!
Feel free to ask any question!

Features:
- Single Layer
44mm * 38mm
5 Buttons ( GPIO-(16, 15, 2, 0), Reset )
18 LEDs ( One for each IO + Power-LED )
USB Port as Power Supply ( external serial needed )
