## 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
