It has plenty of different voltage pinsIt’s not great for complete beginners. As another reviewer stated, there’s no documentation included aside from what’s on the Amazon page and the labels on the device itselfThis makes sense to me, though, as it’s just one of many products based on a chip supported by OpenOCD. If you want documentation, Google the name of the underlying hardware plus the term OpenOCD and you should find what you need for JTAG and SWD. There’s nothing special/unique to this (I don’t mean that as a criticism, I just mean documenting it is probably a bit of a waste of time for the seller/manufacturer)I assume the 2-4 pin UART TTL functionality is straightforward and shows a serial device when plugged in via USB. Haven’t confirmed this but it’s pretty universal behavior ### ⭐⭐⭐⭐⭐ Can avoid purchasing the $1,000 alternative device. *by N***. on July 12, 2022* Was able to program my custom board with this. Just needed to use the nRF Connect for Desktop Software and make sure I was using the right output IO voltage (via the jumpers on the board). ## Frequently Bought Together - ElecBit High Speed USB JTAG Emulator Debugger Programmer V9,CP2102 USB to 5PIN UART TTL,Support 1.8V 3.3V 5V, ARM ARM9 ARM7 Cortex M0/M1/M3/M4, Cortex A5/A8/A9 STM32 STM8 Debug Probes - NOYITO Multi-Function Adapter Converter Board Suitable for JTAG J-Link V8 V9 Ulink2 ST-Link ARM STM32 - Treedix 2pcs JTAG (2x10 2.54mm) to SWD (2x5 1.27mm) Cable Adapter Board Breakout board Jtag Debug Board --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/341534796-high-speed-usb-jtag-emulator-debugger-programmer-v9-cp2102-usb](https://www.desertcart.hk/products/341534796-high-speed-usb-jtag-emulator-debugger-programmer-v9-cp2102-usb) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-04-30*
