   * 4in1 ESCs can be convenient but for the Bolt it is often better to use 4 separate ESC mounted on the arms as this frees up space for decks.
   * If higher then 8A is wanted only connect the signal wires from the ESC connectors to the ESC. Preferably still power the Bolt control board via the battery connector so the battery voltage can be monitored.
+===== Example setup =====
+{{ :projects:bolt:bolt-wiring-example.png?nolink&600 |}}
+===== Configuration =====
+The Crazyflie firmware will automatically detect that it is running on a Bolt and activate the right modules. However some of the configurations still has to be done during compile time and making them run time configurable is currently work in progress.
+===== Current firmware status notes (2019-10)=====
+  * Different PID tuning parameters might be needed for it to fly well. Currently this has to be [[https://github.com/bitcraze/crazyflie-firmware/blob/master/src/modules/interface/pid.h#L34|hard coded]]. Later this will be saved in the EEPROM or in the 1-wire memory.
+  * External battery voltage/current reading is implemented but no logic behind it, so don't run out of battery.
+  * The ESC PWM output is set by default to 400Hz. Use ESCs which can handle this or compile with [[https://github.com/bitcraze/crazyflie-firmware/blob/269730f369b4df34535708d13274abebacb71b5a/src/drivers/interface/motors.h#L92|new value]]. There is also the possibility to [[https://github.com/bitcraze/crazyflie-firmware/blob/269730f369b4df34535708d13274abebacb71b5a/src/drivers/interface/motors.h#L65|enable]] OneShot125 output.
+  * It is wise to do a range test before flying far away.
+  * **Be safe**, it is experimental software. Run all testing **without** props!
