When we designed the Pro-160 hardware we wanted CAN capability so we included a CAN port, but until now we’ve not had the time to write the software for it. But Erica has been burning the midnight oil recently and has now got it working. It means that all operational data can be streamed out, and operational commands for duty cycle, current limit, and regen current limit can be sent in. It will apply to the Pro-100, 160, and 360 models. It will be included in the soon-to-be released 2.5.7 software. It will also need a small CAN expansion board.

Here’s the first prototype of our new brushless controller.

It’s based on our tried and tested Pro-160, so it’s the same size, has the same easy to use software, and a pretty similar feature set. It’s using a larger version of the XMC 1404 processor and a specialist Infineon brushless driver chip.

We’ve added a pedal torque / cadence sensor input so it will be ideal for e-bikes.

Outline specs are 100A and 48V.

This post is just to highlight the changes that have been made to the firmware in the Pro-100 / 160 / 360 range of controllers.

We maintain a full list of them on this page….. https://www.4qd.co.uk/docs/pro-160-360-software-versions/

Note: the words software and firmware are used interchangeably throughout.

We quite often get asked about where to get motors from, so we decided to start stocking a few selected ones. This is the first – a hefty 24V, 750W Italian beauty from Movimotor.

They are available here.

This rugged display / programmer box was designed for those who are installing and programming multiple controllers. It also makes a great floating display that’s a bit more robust.

You told us that you wanted a 50 degree potentiometer for the RBT that lasted longer than the standard one. We built ourselves a test rig and ran a load of the old design through a range of life tests to get some solid data that we could discuss with the manufacturer. To cut a long story short, the manufacturer has created a new potentiometer design with an improved track layout. We have had these running on the test rig for many 000s of operations now, and the ones we have stripped down show negligible signs of wear. Our tests to establish an exact figure will take some time to conclude but early results are very encouraging, and we are pleased to say that these are now available.

All 50′ pots supplied after 4th May 2023 are the new design, they are marked with a black dot on the rear of the casing.

This picture shows the old [top] and new track designs.

Our new Pro-100 has been designed specifically with industrial applications in mind. It’s a little brother to the Pro-160, just as clever but not quite as strong.

This Pro-100 / 160 / 360 remote display box allows the display to be mounted separately from the controller itself for more convenient viewing. It has a keypad to make profile changes and access the advanced functions without needing to access the controller itself.
