You need a segger jlink programmer to use this, USB dfu does not come with the initial bootloader of isp, and nrf52832 has no USB connectivity. nRF52840-dk development kit can be used, and also can double as a dongle for the trackers.
E73-2G4M08S1C (nrf52840), icm42688 or compatible, mmc5983ma
isp1507-ax (nrf52832), icm42688 or compatible, mmc5983ma
Uses nrf52832, no USB, SWD pins on dock connector instead No 0201 parts Removed onboard charger LED is brighter (sink instead of source) * IMU is incorrectly wired
