Overview
The Humane Ai Pin is a screenless, standalone wearable device designed by ex-Apple engineers and manufactured by Compal Electronics. It launched April 11, 2024 at $699-$799 with a required $24/month T-Mobile plan. The Charge Case accessory was recalled in June 2024 due to a fire hazard; the recall does not affect the Pin or Battery Booster. Humane was later acquired by HP Inc.

Processor
The Snapdragon 720G (SM7125-100-AB, codename “Atoll AB”) is a mid-range mobile SoC on Samsung’s 8nm LPP process. It integrates the Snapdragon X15 LTE modem, Spectra 350L image signal processor, Adreno 618 GPU, and 5th Gen Qualcomm AI Engine. RAM and storage are provided by a single Kingston 32EM32-M4DTX29 eMCP package combining 4GB LPDDR4X and 32GB eMMC.
Laser Ink Display
The primary display is a MEMS-based laser projector that projects a green monochrome image onto the user’s palm. It uses two STMicroelectronics piezoelectric MEMS mirrors in a galvo configuration:
- Castor (circular) — Resonant mirror sweeping horizontal scanlines
- Pollux (rectangular) — Quasi-static mirror positioning each scanline vertically
A Lattice CrossLink-NX FPGA coordinates mirror timing with the laser modulation. The projector has its own dedicated PCB with a separate STM32F412 microcontroller. See Components for the full projector board IC listing.

Sensors & Indicators
| Sensor | IC |
|---|---|
| Accelerometer + Gyroscope | STMicroelectronics (6-axis IMU) |
| Magnetometer | MEMSIC MMC5633NJL (3-axis) |
| Ambient Light Sensor | Integrated |
Trust Light: 3 RGB LEDs on the front face indicating camera/microphone activity. Driven by an STMicroelectronics LED1202 12-channel driver.
Beacon: 1 RGB LED for status/notification, also driven by the LED1202.
Form Factor
The system consists of two magnetically coupled halves that sandwich the user’s clothing:
- Ai Pin (outward) — All compute, sensors, and projector. 47.5 x 44.5 x 15mm, 34.2g.
- Battery Booster (inward) — Battery + wireless charging transmitter. 47.2 x 45.2 x 8.3mm, 20.5g. Hot-swappable without powering down (the Pin’s internal battery bridges the gap).
The front face has the camera, depth sensor, projector aperture, Trust Light, and a capacitive touchpad for gesture input. An STMicroelectronics STWLC86 wireless power receiver in the Pin receives power from the Booster through fabric.
Colors
| Color | Finish | Price |
|---|---|---|
| Eclipse | Matte black | $699 |
| Equinox | Polished silver, black touchpad | $799 |
| Lunar | Polished silver, white touchpad | $799 |
FCC Label
The Ai Pin uses an electronic label (e-label) displayed via the laser projector rather than a physical label. FCC IDs: 2BAFM-HU123 (Pin), 2BAFM-HU223 (Booster).
Charging
- Charge Pad — Desk charger for Pin + Booster. Has a pinhole reset button on the underside.
- Charge Case — Portable case holding the Pin and two Boosters. Charges via USB-C. Recalled June 2024 due to battery fire hazard.
Environmental Limits
Operating temperature 5-35°C. Maximum altitude 3,000m.
