Disassembly

Full disassembly photos, SPI chip details (Macronix MX25L25673GZ4I-08G, 32MB WSON-8, 3.3V), programmer setup, and step-by-step flashing instructions are maintained by Dasharo:

→ Recovery & disassembly photos → Initial deployment → Hardware matrix

Flashing

Key notes: This board ships pre-flashed with Dasharo and Heads from NovaCustom/Nitrokey — external flashing is not required for normal operation. The Dasharo external-flashing instructions cover both initial deployment and unbricking/recovery — see the Dasharo NovaCustom initial deployment and Dasharo NovaCustom recovery documentation.
