I've built several terminal boards over the years. While the font isn't as nice as some others, this simple terminal board has many advantages. It uses easily available thru-hole parts, the source code is freely available, and it supports a wide range of baud settings.
The credit clearly goes to others for the design. I wanted to learn KiCad so used this as an opportunity to complete a simple project.
Please enjoy!
I have uploaded the gerber files to PCBWay to make ordering easy. Current cost for 5 boards with shipping to the USA via DHL is $22:

V2.0 changes the RS232 driver to a MAX3232 which will output the correct 3.3v levels for the PIC32. No trace cuts or modifications are required. Also Capacitors C8-C12 can be either 1.0uf or 0.1uf (they are 1.0uf on the PC board and BOM).
What kinds of caps did you use? I have these caps laying around:
A - electrolytics, Nichion, for c3, c4, c7 (10uF)
B - tantalums, polarized, for c8, c9, c10, c11, c12 (1uF)
For A, is it a big deal they are not tantalum?
For B, is it a big deal to use tantalums instead of ceramic? Polarity for C8, C9, C10 and C11 is obvious. C12 it should be + on the ground side, other side to -VSS? If not I'll find ceramics.
