This is based on the design by ArcadeTV.

This design expects you to have a properly attenuated cable.

This design can be used by either removing the RF Modulator from your SMS/MD/Genesis or by just using 3M tape and securing it elsewhere.

Resistor values for all models are on the rear silk screen.

-1.35V LDO regulator for to modify a Pentax Spotmeter 1º/21º (tested on version II). You will need two resistors: a 100kOhm and a 13.7 kOhm, both in SMD 0603 package, and a 2.2uF capacitor (though I used a 10uF because the 2.2uF was out of stock). Here is the list of components that I used:

LDO regulator - TPS72301DBVR

Tantalum cap - F381A106MMAAH1

100kOhm res - ERJ-3EKF1003V

13.7kOhm res - ERJ-3EKF1372V

Note that the PCB has pads for an input capacitor as well, but it is not needed (in fact, it is not recommended, since when I tried it the circuit was not working.) You can find some pictures of the board in the spotmeter on my blog.

This adapter can be used to connect a Black Magic Probe JTAG/SWD programmer and debugger to the legacy ARM 20Pin JTAG connector. The adapter can accept male, female connector in streight and right angle configurations. Both connectors are through hole connectors. This is an older design that was replaced by the 20Pin JTAG/SWD Adapter half SMD.

This adapter board design is part of the 1BitSquared adapter collection.

This adapter can be used to connect a Black Magic Probe JTAG/SWD programmer and debugger to a PMOD interface popular on FPGA development boards. When using an IP core with JTAG/SWD interface this adapter makes it easy to connect an ARM Cortex type Debug cable to your FPGA project.

This adapter was originally designed to interface the Black Magic Probe JTAG/SWD programmer and debugger with SiFive E310 RISC-V evaluation bitstream running on the Xilinx Arty evaluation board.

This adapter board design is part of the 1BitSquared adapter collection.
