We have updated the M0129 in the past few months to support 2S-6S, it looks like the datasheet is out of date. Thanks for pointing that out.

If it is marked M0129-63 or M0129-65 it supports 6S

M0129-3 and M0129-5 are the older version and they only go up to 4S

@Vinny Yes, thank you very much!

Here are the links to the test firmware:

M0129-3
M0129-6

After you update, you should see the following version after running voxl-esc-scan.py (except yours will be M0129-6). The firmware version will be 39.23 and this version will be reserved only for this test firmware:

INFO: ESC Information: INFO: --------------------- ID : 0 Board : version 40: ModalAi 4-in-1 ESC (M0129-3) UID : 0x2039333557555304003F0029 Firmware : version 39.23, hash 30c088dc Bootloader : version 184, hash 10bf24c8 ...

In case you need help updating ESC firmware: https://docs.modalai.com/voxl-escs/faq/#q-how-do-i-update-esc-firmware

We won't officially release this firmware version in order to avoid the aforementioned risk of turning on 5.0V by just installing a firmware update, however we will work on enabling this in the ESC params.

Also, just as a reminder, please be careful soldering to the AUX test points, use high quality flexible cables, and use strain relief to avoid lifting the pads.

Hello @LV-Office-Holder,

The M0138 racing ESC only has two I/O pins and they are used for aux PWM output. PWM input is disabled for this ESC due to lack of PWM input for each ESC channel.

The ESC protocol example can be found here : https://gitlab.com/voxl-public/support/esc-driver as well as part of PX4 implementation : https://github.com/modalai/px4-firmware/tree/voxl-dev/src/drivers/actuators/voxl_esc . I would suggest referencing the PX4 implementation since it has the latest updates.

Additionally, we have voxl-esc test tools (python) : https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-esc . The test tools allow you to spin motors, plot data, perform firmware and parameter updates.

Please let me know if you have any other questions.

Alex
