RGB SCART daughter board for the IF-C01COMG Clone board. This board also has support for a sync stripper circuit selectable by SW2. If enabled the LED in D1 will light up. Supported sync strippers are LM1881 and EL1883 (and whatever other pin compatible). LM1881 supports running directly off 12V and thus if using this, close the JP1 jumper with solder, and you can then skip U2 and its two capacitors C5 and C6. EL1883 runs off 5V, which must then be supplied by U2, and JP2 then needs to be closed instead. THEREFORE ONLY CLOSE EITHER JP1 OR JP2, NOT BOTH!

This is Rev. B with the stereo-to-mono fixed properly.

SW1 selects to route audio to stereo RCA plugs or to internal mono audio.

SW1 and SW2 can also be omitted and jumped accordingly (the switches are quite expensive…)

Connect the two boards with a Molex 15267-0300 FPC cable (Mouser P/N: 538-15267-0300)

The mechanical slots for the SCART plug are hacked in due to OSHParks missing oval slot support. It should be good though.

RGB/YPbPr input card for JVC professional monitors like TM-H1950CG. Based on the original card, thus all resistors and capacitors have same reference ID as the original card. Only the power supply part is different. This is the base board, which supplies the actual “interface” electronics. You then need one of the input boards mentioned in the bottom of this post, OR solder directly to the pads on this board. If you’re not into SMD’s there’s a through-hole version here: https://www.oshpark.com/shared_projects/NHivAGjf

Adapter plate for TL866 programmer when only a TSOP-48 version of a SOP-44 chip exists in the programmer software, example is the MX29LV160T flash. It is designed to be used with the “original” TSOP-48 base plate and the “original” SOP-44 adapter board.

You need two 2x12 male pin headers with 2.54mm pitch for the connection to the SOP-44 adapter and two 2x12 female pin headers with 2.54mm pitch for the base plate connection. These can be found on Aliexpress and eBay at next to nothing.
