GrblHAL-Sender
About the GrblHAL-Sender PCB
GrblHAL-Sender is an open source PCB design by Jay-Tech, published on GitHub. It is a 2-layer board measuring 70 × 92 mm, with 47 components from 16 distinct parts.
Other key parts include the LTV-817S-TA1-B. By type, the board carries 21 resistors, 5 transistors, 5 diodes, 4 ICs, 4 connectors and 4 LEDs.
From the project
Four-channel opto-isolated high-side switch board. 70 × 92 mm against v1's 150 × 115 — 64% less area, same circuit per channel.
Four-channel opto-isolated high-side switch board. 70 × 92 mm against v1's 150 × 115 — 64% less area, same circuit per channel.
Generated and placed, not routed. DRC is clean on the placement; the routing is the work left to do, exactly as v1 was at this stage.
Unchanged: the entire channel circuit. Same optocoupler, same AO3401A, same 8.2 V gate clamp, same resistor values. That is the point — v1's bench-test procedure validates this board too, and the one part of the design nobody has watched work does not get disturbed by a packaging exercise.
