Mini-I/O 16
|
|
===========
|
|
|
|
This is a small board with 16 LEDs and pairs of switches for exercising
|
|
digital circuits. It can draw power from the circuit under test, or it can
|
|
use USB-C. It's intended to run at 5V, but the high-level threshold for
|
|
AHCT logic (the LEDs are buffered by two 74AHCT240s) is wide enough that it
|
|
might work at 3.3V as well.
|
|
|
|
v2.0 replaces the SMD headers with through-hole headers, as the SMD headers
|
|
tended to break off easily.
