I got old enough that people now expect me to give them a business card.
It seemed boring to have just a regular business card so I decided to design a PCB one.
It was designed in Eagle and I put all the information in white silkscreen on matt black soldermask.
I added a little prototyping area on the right half.
Ideally, the board would have a simple circuit or microprocessor dev board on it in the future. I am still looking for something that will be simple enough that it won't make me go bankrupt after ordering 100pcs. A working circuit would be also more understandable for people who are not electronics geeks.
- 5V to 3.3V converter (nice, because it's doable in all SMD parts)
- op-amp dev board (nice, because it's cheap and useful)
- FTDI UART to USB (useful but expensive)
- Adafruit teensy board
- USB hub
- TSSOP adapter
- SMD proto board
- micro SD card reader
