This plug thing is starting to become addictive…
I’ve been working on another set of plugs, to extend the interfaces further. Here’s a preview of a few new ones, all using I2C and daisy-chainable:
From left to right:
- UART Plug – a serial port with 64-byte RX/TX buffers and RTS/CTS lines
- Analog Plug – 8 analog inputs with 12 bit resolution
- LCD Plug – a piggyback board for LCD displays with a standard 16-pin header
Most of these plugs will have jumpers to allow connecting more than one of them to the same port (as I2C bus). So within the limits of power consumption, I2C bus lengths / loading, and processing bandwidth, this should allow for quite a bit of extensibility.
