Super Simple PIC 16x84 Development Board
Table of contents
When developing devices with the popular PIC 16x84 from Microchip you will sooner or later need
a testboard. This board can be used for this purpose. It's equiped with 2 keys, 4 leds, a
RS232 interface and a socket for a serial eeprom. Using jumpers it can be configured in some
ways. There is also a prototyping area available on the board which could be used for custom
extensions. This was used to add a LCD as you can see on the pictures below.
