# AS5600 with a Raspberry Pi Pico

The AS5600 talks to the Raspberry Pi Pico over I2C0 on GP4 (SDA) and GP5 (SCL), the arduino-pico core's default Wire pins, at its fixed address 0x36. The page powers the module from 3V3, which keeps its pull-ups at the Pico's logic level but puts the chip in its 3.3 V mode, so check how your breakout routes VCC.

## Wiring

| AS5600 | Raspberry Pi Pico | Note |
| --- | --- | --- |
| VCC | 3V3 |  |
| GND | GND |  |
| SCL | GP5 |  |
| SDA | GP4 |  |

## What to know on the Raspberry Pi Pico

- The AS5600 has two supply modes: 4.5 V to 5.5 V on VDD5V, or 3.0 V to 3.6 V with VDD5V and VDD3V3 tied together. Breakouts route VCC to VDD5V, so on the Pico's 3V3 confirm yours bridges the two pins before trusting its readings. (ams AS5600 datasheet v1-06, pp. 5, 9)
- It draws 6.5 mA always on, a small share of the 300 mA Raspberry Pi recommends as the limit for the 3V3 pin. (ams AS5600 datasheet v1-06, p. 5; Raspberry Pi Pico datasheet, release 21, p. 8)
- Its address is fixed at 0x36. For two encoders on one Pico, put the second on I2C1 with Wire1, since the RP2040 has two I2C controllers. (ams AS5600 datasheet v1-06, p. 10; Raspberry Pi Pico datasheet, release 21, p. 4)
- The AS5600 also outputs the angle as a voltage on OUT. On the Pico that pin would go to GP26, GP27 or GP28, the only ADC inputs, and must stay within the 3.3 V rail. (Raspberry Pi Pico datasheet, release 21, p. 19)

## Questions

### Does the AS5600 work at 3.3 V with a Raspberry Pi Pico?

The chip does, in its 3.3 V mode (3.0 V to 3.6 V) with VDD5V tied to VDD3V3 (ams datasheet, pp. 5, 9). Many breakouts feed VCC to VDD5V only, so check the board before running it from the Pico's 3V3.

### Can I read two AS5600 sensors with one Pico?

Not on one bus: the address is fixed at 0x36 (ams datasheet, p. 10). Use the Pico's second I2C controller (Wire1) for the second sensor, or an I2C multiplexer.

### Why does my AS5600 report no magnet on the Pico?

The magnet must be diametric and 0.5 mm to 3 mm above the chip (ams datasheet, p. 33). If isConnected() fails instead, check SDA on GP4 and SCL on GP5.
