A simple breakout board for using the MT6835 magnetic encoder.
How to use the board
See schematic for more details
Inputs/Outputs
The connections are broken out into 3 JST-PH connectors
- 6 pin: SPI and power input (mandatory- need 3.3 or 5V to power board)
- 4 pin: ABZ/PWM output
- 3 pin: UVW output
The thinking being you will need to connect via SPI to configure the encoder no matter what, but likely you'll use either ABZ or UVW for monitoring position.
How to order
The BOM for this design was optimized around in-stock JLCPCB parts. To order this board, simply make a zip of the "JLCPCB" folder and upload to the JLCPCB order page.

Questions
How big is the Magnetic encoder PCB?
It measures 30 × 30 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Magnetic encoder use?
10 parts, built around the MT6835GT-STD-R and SMAJ6.0A. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Magnetic encoder KiCad files?
From the another-greg/MT6835_encoder_breakout_board repository on GitHub, at the commit this page was made from: the board is magnetic_encoder.kicad_pcb and its schematic magnetic_encoder.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Magnetic encoder design in my own project?
Its repository states no licence, so its author keeps all rights: ask another-greg before reusing the design.
