## Wiring
- For the NAZE, no external wiring is necessary. Simply plugin the board via USB cable.
- For the NAZE, no external wiring is necessary. Simply plug in the board via USB cable.
- For the CC3D, connect [a USB to UART adapter](http://bit.ly/cf-cp2102) to the main port. If you need one, I prefer the [CP2102](http://bit.ly/cf-cp2102) as it is cheap and [the driver](https://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx) is readily available.
- For the CC3D, connect [a USB to UART adapter](http://bit.ly/cf-cp2102) to the flex port.
- Ensure MSP is enabled on the flex port. Unfortunatly the main port cannot be used in the current configuration due to the inverter on this port.
- You'll only need this connection to the CC3D, do not plug in the normal USB connection.
- If you need one, I prefer the [CP2102](http://bit.ly/cf-cp2102) as it is cheap and [the driver](https://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx) is readily available.
- In the case that your board does not power on fully without a battery attached, it is OK to attach the battery before following the steps below. However, it may not be necessary in all cases.

@ -4,7 +4,7 @@ The DoDo board is a clone of the SPRacingF3 board in terms of CPU pin mappings.
Hardware differences compared to SPRacingF3 are as follows:
* The CPU is the cheaper version of the F3 with only 128KB FLASH.
* Rev 1 and Rev 2: the CPU is the cheaper version of the F3 with only 128KB FLASH. Rev 3: the CPU is a F3 version with 256KB FLASH.
* The external flash rom is the same size as found on the Naze32 (2MBit)
* The barometer is the cheaper BMP280.
* It does not have any compass sensor.
