DIY ArduMower Brushless Driver Kit

In this chapter you will find the information about the DIY ArduMower Brushless Driver, based von TI DRV8308 Chip.

General Information about the ArduMower Brushless Driver like architecture and furth options, you will find in another WiKi [1]

Description

DIY ArduMower Brushless Driver, this is a not configured Driver, as it comes out of the factory. It is for experts, able to program there own configuration to the device. It is needed if you want to use another mower than an ArduMower with other types fo motors. For this, you need expert knowledge about electronics / brushless motors and software skill. With this kits, you are working on you own risk.

One IMORTANT notice at the beginning: The OTP ROM, where you have to store the program parameter for your motor, can programmed only ONE time! OTP-ROM changes afterwards are not possible. So please think twice before you burn the parameter into OTP-ROM. More on this later in this article.

Building the SPI Brushless Driver Programmer

Before you start the assembling of the Driver Board, we will build the programmer. To build your own programmer for the controller DRV8308, you need an Arduino Nano and a 5 pin JST-XH plug with cramped wires. Solder the wires as shown in the picture and ready is the programmer hardware.

Connector Pinout

Building the PCB and connect the cable

Step 1 Soldering :

Okay, you are an expert, you do not need an Instruction how to solder some parts on a PCb. Lets go to step 2

Step 2 Connect the Brushless Motor :

Step 3 Connect the Power :

Also easy for you, connect the power cable, but switch the power off before! Please take care that you have the right polarity! The +24V power to the connector marked + and the ground pole toe the connector marked - . Check it twice! If you do it wrong, the 3.5A fuse on the board will blow up and you have to change it.
