LEDIO
About the LEDIO PCB
LEDIO is an open source PCB design by Defdist, published on GitHub. It is a 2-layer board measuring 272.5 × 12 mm, with 19 components from 10 distinct parts.
Other key parts include the TCS40DPR. By type, the board carries 7 diodes, 5 connectors, 4 resistors, 2 capacitors and 1 IC.
It belongs with the robotics & motion, displays & leds and dev boards & breakouts designs in this gallery.
From the project
Uno Shield for grblDD: closed loop spindle VFD + 4 stepper drivers
Main Controller PCB for GG3. Hardware version 3B This is the 1st PCB shipped in GG3.
Changes (from the previous prototype PCB):
-3-pin header order changed from VGS to VSG (e.g. from +-X to +X-). This creates an incompatibility issue with GG2 units, which will require a pin swap.
-Removed Door Switch (which also restored previous gap for zip tie).
-Vref changed to 1.78 volts (added 1k series with pulldown).
