Allows logic level drive of external high voltage circuits. Thanks
Opto coupled (galvanic isolated) outputs.
Designed for a front panel control/status system. Boards look great. Really like the blue solder mask. Thanks.
Regulator mounts through hole. Improved layout over past versions. Accepts all fixed voltage regulators in the MC78xx family of parts. Thanks for the excellent work.
Board appears flawless. Assembled no problems. Ffunctions as expected. Thanks!
Couldn't find an spi-to-lcd interface so we designed one. No problems. Worked as expected first time. Thank You.
Excellent!
Six adjustable (at assembly) debounce circuits.
Four SPI-connected eeproms with SSI selector.
Eight pushbutton debounced circuits with 8 bi-color led status indicators. Thanks
Regulator mounts through hole. Improved layout of previous version. Looks godd. Works good. Thank you!
Added on-board +12v to 5v regulator to allow the module to be independent of the uC regulator and also to be seperated to allow mounting on a front panel. Also added PWM control to the backlight circ...
Excellent production.
Implements EIA/TIA-485 transceiver with status lamps and multi-drop network interface.
