F722-SE DPS310 Ver.
-
F722-SE DPS310 ver. and previous BMP280 version have same layout and components except for barometer & battery pads style.
- INAV2.5.x and Betaflight 4.2.x downloaded from configurator don’t support new barometer DPS310.
- DPS310 has been supported officially by INAV2.6/ BetaFlight 4.3 and new configurator.
- For now, pls download customized BetaFlight 4.2.x from top-right “Firmwares” link
