AVR ATMEGA328P Project Board – Part 2 – PCB Roughing

Welcome to part 2 of the series. In this video, we actually reference the building out of a blank 50x50mm rounded corner board with M3 hole mounts. Since I already had a video like that posted up, I didn’t want to use up too much time to duplicate content. Folks who want to check it out can do so. Rough Placement So the TLDR; of this video segment is that we place parts on the board roughly where we want them to be. Ie, We might want the MCU in the middle of the board so it’s easy to route to it from anywhere? We want the headers for Serial, I2C, GPIO, and ADC to be on the outer edge, where it will be easier to access. We…

ESP8266 Pogo Pin Programming Jig

Wing Pogo Pin ESP8266 Programming Jig

So, at some point in time, I was going to program a bunch of ESP8266 modules for resale with some custom code. Going through that experience has taught me to do more analysis before jumping in with payment in hand. 🙂 One of the things I did to try to make the process more tolerable was a programming jig for ESP8266 modules. I happened to have purchased a whole bunch of D1 Mini style modules where the ESP8266 modules sat on a small programming carrier board. It occurred to me that I could reuse the carrier board as a programming rig, and just program the ESP8266 modules themselves… if I had some kind of pogo pin jig. Notes: Circuit and PCB designed in Autodesk Eagle Circuit board manufactured…
