Pi MATRIX LED Matrix for your Raspberry Pi (KIT VERSION) GPIO

The Pi Matrix is a fantastic tool for learning GPIO programming on the raspberry pi. Sure, you could hook up a few LEDs and switches instead, but why do that when you can program a huge matrix of 64 LEDs? If you are like me, and ready to learn about GPIO, this is the first kit you should get. Why? - It’s fun. - It’s compact: Just pop it on top of the pi - It’s clean: no need for a breadboard or wires - It’s safe(r) for your pi: does not use unbuffered GPIO pins - It’s a great excuse to get out your soldering iron. - It’s an easy way to learn about i2c on your pi - Did I mention that it’s fun? As a huge bonus, just remove the LED matrix and you are left with 16 new, buffered I/O pins to command. Kit requires assembly. Simple soldering.

Doc fetch goes through Layer's Aerospike pull-through cache; cache hit served the row without touching turbopuffer. The similar query asks Layer for nearest neighbors of the stored product vector — queries don't go through the doc cache, so no cache header is set.
