Brushless Adapter
ArduMower Brushless Adapter
The ArduMower Brushless Adapter (BLA) is to connect the Brushless Driver with the PCB1.x. The BLA has already the Version 1.1. It fixes a motor start if you pull the flat cable. Therefore, you must pay attention what combination of BLA and BL Motor Driver you have. You can find the Versin Nr in the lower left hand corner.
ArduMower Brushless Adapter V1.0 (Stand10.01.2021) with BL Motordriver 1.0 (Stand 20.04.21)
This runs without any change. BUT please take care that the flat cable is connected when you power on the mover! It is recommended to fix the flat cable connector proper in the socket with a little spot of glue / hot glue! Reffer also to the Bug Fix at the end of this page, this fix is needed.
ArduMower Brushless Adapter V1.0 (Stand10.01.2021) with BL Motordriver 1.1 (Stand 20.04.21)
For this combination you must solder 2 resistors ( 680 Ohm - 1k Ohm) to each flat cable connector. The resistors on Pin 2 (Enable) and Pin 7 (PWM Signal) are pull ups to +5V.
ArduMower Brushless Adapter V1.1 with BL Motordriver 1.0 and BL Motordriver 1.1
This runs without any change. Also the Bug Fix (220nF Odometry Entry) is not needed. If you have the 220nF on the PCB, please remove. You can mix. V1.0 and V1.1 BL-Driver. Take cate about the " BUT please take care... " remark for Adapter V1.0 with BL Motordriver 1.0. This is still valid for all V1.0 BL Driver (not BL Driver V1.1) connected to the V1.1 Adapter.
Bug fix
if you use ArduMower Brushless Adapter V1.0 (Stand10.01.2021): The odometry divider on PCB 1.x caused a problem with the BL odometry signal. The ArduMower will drive not synchronized, one wheel is slower. You can fix it with a 220nF an each ot the odometry inputs. Take care that you use the latest version of sunray SW.
Not needed for Brushless Adapter V1.1 or higher.
At the motor connectors solder BOTH pins, not only one, because of high curent.
