The lamp board of pico matrix has not yet
reached the 3535 and 1209 lamp beads used by micro, and it is almost used up
. The lamp beads of the ws2812 main control are so expensive.
Then Xianyu found that the full-color dot matrix used in LED large screens
bought the p10 first, with a resolution of 16x32, 8 pieces of free shipping, and 0.015 yuan per point... The 0807 packaged ws2812 lamp beads are 0.16 yuan, The thief is cheap.
Then I found a library https://github.com/2dom/PxMatrix and
used esp8266 or esp32 to drive.
Solder according to the wiring requirements, and ran the demo to
start
The effect is quite good, that is, it consumes
a lot of power. The 5v6a power supply originally bought for the lock control board, the lock control board is not ready yet, and it is used.
The p2.5 lamp board
should save a little electricity on the road. It’s
not easy to say that I bought a 32x64 lamp. The lamp beads are 4 times this.
Try to do the conversion of ws2812 to hub75 protocol. This awtrix lamp board can save a lot Money...
