+==== iNav@CC3D ====
+Ces cartes ne sont plus supportées par iNav, la dernière version qui supporte les CC3D (carte F1) est la version **1.7.3**.
+Pour que le GPS marche, il faut le [[https://librepilot.atlassian.net/wiki/spaces/LPDOC/pages/5669417/Configure+a+GPS+for+CC3D | configurer]], certains GPS ublox n'ont pas d'EEPROM, mais [[http://www.pial.net/crius-cn-06-gps-v10-module-eeprom-mod/ | on peut ajouter une EEPROM I2C]] !
+==== I2C bus speed selection ====
+Some sensors (especially cloned barometer/compass sensors) are reported to work unreliably on default 400kHz speed.
+New **//i2c_speed//** setting allows to reduce I2C clock rate to 200kHz and 100kHz to allow these picky sensors to function properly.
+Overclocking to 800kHz is also possible but not recommended.
+If on your board compass/baro sensor is not recognized or hangs (usually indicated by rapidly increasing I2C error count) please try setting i2c_speed to 200KHZ before reporting a bug.
