About the CACKLE-nanoSPI-MA735 magnetic encoder PCB

CACKLE-nanoSPI-MA735 magnetic encoder is an open source PCB design by techy-robot, published on GitHub under the CC-BY-NC-4.0 license. It is a 2-layer board measuring 5.7 × 105.5 mm, with 4 components from 4 distinct parts.

Other key parts include the MA735GGU-Z. By type, the board carries 2 capacitors, 1 IC and 1 connector.

It belongs with the sensors designs in this gallery.

From the project

This is a super compact SPI magnetic encoder, with the flex cable being 2.4mm wide and 100mm long, and the tip around 5.6mm diameter. It is quite simple, and supports on shaft or side-shaft mounting with correction.

This is a super compact SPI magnetic encoder, with the flex cable being 2.4mm wide and 100mm long, and the tip around 5.6mm diameter. It is quite simple, and supports on shaft or side-shaft mounting with correction.

It supports a max of 25mhz bus speed, though practically speaking this is closer to 20mhz. It supports SPI mode 0 or 3, detecting automatically.

The sensor itself, MagAlpha MA735, has some quirks to it. It is variable resolution ranging from 9 to 13 bit which is inversely proportional to its speed. If you want the max measurement speed at 60k rpm, then you will have to read…
