This board enables Composite Video output from the ColecoVision. This is only compatible with the NTSC model. All SMD packages are 0805 for easy soldering. This is the same as the v1 board essentially but all SMD and cleaner overall.

R1: 75Ω

R2: 10kΩ

R3: 10kΩ

C1: 47uf (Tantalum Case B)

C2: 27pf

This board can be used to easily create the necessary circuit for outputting composite video on your TurboExpress or PC-Engine GT.

This board is designed to allow only a screen mod or AV out, not both.

Please note that you do need to lift and ground pins 19, 25, 29, 32, and 39 on the HuC6260 to enable composite video. Big thanks to thesteve of PCEngineFX forums for the circuit schematic.

To keep the board small, consider ordering it as .8mm thickness. Also note this board is designed to use 2n3904 equivalent SMD transistors. If you want to use A/V out, a different board is necessary.

Half Inch version of the Micro-USB Breakout board. Much easier to work with but larger and a bit more costly.
