The Charliewatch is an “analog” watch with 60+12 Charlieplexed LEDs. Based on Travis Goodspeed’s GoodWatch21 schematic, using the CC430F5137IRGZR CPU, which doesn’t have the LCD controller of the CC430F6xxx in the GoodWatch. There are also pads for a six pin Launchpad for programming or serial communication.
