Robot joints and actuators
14-bit absolute angle over SPI reports the joint position at power-up without homing, and works up to 28,000 rpm; the diametric magnet sits on the shaft end with no contact.

Guidance to help you shortlist. The basis is shown for each recommendation.
14-bit absolute angle over SPI reports the joint position at power-up without homing, and works up to 28,000 rpm; the diametric magnet sits on the shaft end with no contact.
Engineering inferenceSPI absolute angle plus ABI quadrature (1000 PPR / 4000 CPR) and UVW commutation outputs give a BLDC/FOC driver both position and commutation signals.
Engineering inferenceNo-load speed, rated performance and stall limits describe different operating points. A stall specification is not a continuous operating rating.

Resolution, output stage and the pads you wire — what the controller needs to count it.
| Pad / pin | Position | Role | Notes |
|---|---|---|---|
| 5V | P1-1 | power in | positive supply (sensor pin 11 VDD); 4.5–5.5 V in 5 V mode, or 3.0–3.6 V with JP1/R2 set for 3.3 V |
| 3V3 | P1-2 | other | 3.3 V LDO output (sensor pin 12 VDD3V); not for other loads |
| NC | P1-3 | other | not connected |
| CSn | P1-4 | select | SPI chip select, active low (sensor pin 1) |
| CLK | P1-5 | clock | SPI clock (sensor pin 2) |
| MOSI | P1-6 | data | SPI MOSI (sensor pin 4); tie to VDD for read-only 3-wire angle reads |
| MISO | P1-7 | data | SPI MISO (sensor pin 3) |
| GND | P1-8 | ground | ground (sensor pin 13) |
| B | P1-9 | signal b | incremental quadrature B (sensor pin 6) |
| A | P1-10 | signal a | incremental quadrature A (sensor pin 7) |
| I/PWM | P1-11 | index | index pulse I, or PWM angle output (sensor pin 14) |
| TEST | P1-12 | other | test pin (sensor pin 5) |
| NC | P1-13 | other | not connected |
| W/PWM | P1-14 | other | commutation signal W, or PWM angle output (sensor pin 8) |
| V | P1-15 | other | commutation signal V (sensor pin 9) |
| U | P1-16 | other | commutation signal U (sensor pin 10) |
CPR counts both edges of both channels on the sensed shaft; on a gearmotor multiply by the gear ratio for the output shaft.
No-load, rated-load and stall figures retain their separate test conditions.
Stall torque and current are not continuous ratings. Check the duty cycle and starting load when choosing the driver and power supply.
Product operating conditions, chip ambient ratings, package case limits and junction maxima remain separate.
Reported product dimensions may exclude protruding components. Unknown height does not establish a complete clearance envelope.
Attached generated geometry is an approximate envelope. A generated outline does not establish an electrically verified PCB footprint.
