Opening the unit: low difficulty
- Ordinary circuit board in a sealed cast aluminium housing, no gel.
- Direct access is a JTAG connection on a group of small pads beside the processor, soldered or made with a spring-pin adapter.
- Normally read and written through the diagnostic socket; opening is only for a full backup, a clone or recovering a failed write.
Advice: If you open it, do not force the cover, keep the power supply stable while you work, and reseal it afterwards.
General information: units with the same name can differ. Follow your tool's connection guide.
