JackAl Display Protection


Jack Purdum
 

All:

Al has made the Gerber files for his RA8875 display protection board available to all who might be interested. The Gerber files and a documentation file are in the attached zip file. I will also post these in the Files section of the JackAl group. The circuit is sufficiently simple it can also be constructed from perf board. This is the BOM for the PCB, which uses SMD parts.

Components are as follows:

  • R1 Thru R5?? 10 ohms? 1206 SMD
  • R7? 200 ohms? 1206 SMD
  • R6? 18 ohms 1206 SMD
  • IC1 ¨C IC4?? ¨C RB731U Schottky diode array from Arrow Electronics
  • C1? 0.1 uF 1206
  • C4? 10 uF SMD
  • J1? 2x5? IDC or equivalent
