4 Digit Up/Down Counter
Kit
This is a low cost 4 digit
Up/Down Counter. Count range is from 0000 to 9999 (counting up) or 9999
to 0000 (counting down). The overflow output pulses low when count wraps
around to zero. This allows two counters to be connected together
to make an 8 digit counter. Good example of an Atmel AT90S1200 -
DIY Kit 129.

- L: 2-1/2" W: 2" H: 1/2"
- Requires external
9-12 volt dc @ 40mA power supply
