The ProMicro nRF52840 is the lead board and has its own document. The other
packaged boards share the same package model; their identities and notes are
summarized below, and the authoritative pin/peripheral truth lives in
boards.txt and the per-board variants/ files.
- promicro_nrf52840.md — AliExpress ProMicro nRF52840; the lead board with end-to-end hands-free upload, single-cable debug, and BLE GATT (Windows/Android/board-to-board) verified on hardware.
- nicenano_v2 — nice!nano v2; same UF2 / Adafruit serial-DFU family, secondary buses modeled, not yet re-verified on hardware here.
- supermini_nrf52840 — SuperMini nRF52840; nice!nano-class bootloader identity, secondary buses modeled.
- nrfmicro_nrf52840 — nRFMicro; pid.codes identity, secondary buses modeled.
- mini_nrf52840 — generic AliExpress mini module; identity varies by seller.
- xiao_nrf52840 — Seeed XIAO nRF52840 / Sense family model.
- pitaya_go_nrf52840 — Makerdiary Pitaya Go model.
- devboard_nrf52840 — generic nRF52840 dev board; official Nordic DK route is SWD/J-Link.
- devboard_nrf52833 — generic nRF52833 dev board; SWD-first package model.
- usb_dongle_nrf52840 — PCA10059 USB dongle; Nordic Open DFU, not the package's UF2 / Adafruit serial-DFU path.
verified: checked on real hardware.modeled: derived from the current package, variants, and smoke tests.reference-core: derived from a trusted reference implementation rather than direct hardware proof.partial: coherent package behavior exists, but the board-level evidence chain is incomplete.
