One nRF52840 variant shared across both radios, picked per env: Duo runs the LR1121, Uno the SX1262. Same PCB, only the radio and its DIO1 pin change. SuperIO adds the SH1107 OLED, GPS, buzzer and joystick. GPS is driven by the 3-position mode switch (Mode 2 = on), polled live the way thinknode_m1 does it. Five quick user-button presses power the unit off; a press wakes it back on (arms the button as an nRF52 GPIO SENSE source before SYSTEMOFF). Consolidates #2054 and andyshinn's shared-base/uno work, rebased on dev. Co-authored-by: lbibass <ewdries02@gmail.com> Co-authored-by: Andy Shinn <andys@andyshinn.as>
