For our SMD March workshops I chose Ishan Keribar’s Embedded Ethernet Gateway. I added an FT230X and usb port with a Arduino uno style reset on CTS (230X has no DTR but avrdude toggles both). I also used a SOB 5050 template to make cases easy to design. By adding an 8MHz variant to the Arduino board config you can then download sketches like a Arduino – this is a little more accessible than a STK500. Unfortunately I made two errors on the PCB, they’re fixed by cutting tracks as seen in the photos.
