## Questions & Answers

**Q: Does it come with the cable to go from this board to the target board?**
A: Yes and a UART breakout cable.

**Q: Can this product be used for swd with an arm processor?**
A: Yes, the Black Magic Probe does support SWD as well as JTAG.

**Q: Can i use this with a saml21 and mplabx?**
A: Should be able to, as the data sheet for the SAML 21 states "two-pin Serial Wire Debug (SWD) programming, testing, and debugging interface" which the Black Magic Probe does support (as it supports SWD and JTAG).

**Q: Can this be used to program nrf52832?**
A: Yes, the nrf52832 is a SoC based on a Arm cortex-M4 CPU. The Jeff Probe runs a modified version of the black magic probe firmware, which is designed to debug/program most ARM CPUs

## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Nice cheaper alternative to the Black Magic Probe
  

*by B***S on Reviewed in the United States on 9 July 2020*

A great little debug probe that is comparable to the official black magic probe with a less powerful mcu.  The price reflects this, however.Of course, you could always flash the BMP firmware onto a cheap stm32 dev board, but I'd rather buy this because it comes in a very compact form factor and provides the handy UART port as well.

### ⭐⭐⭐⭐⭐ 







  
  
    Cool.
  

*by G***E on Reviewed in Australia on 18 February 2023*

Cheap and functional! Highly recommended.

### ⭐⭐⭐⭐⭐ 







  
  
    Neat little black magic probe
  

*by K***T on Reviewed in the United States on 7 March 2020*

Well made.  Great price.
