Hall Sensor Wireling
DESCRIPTION
This Wireling lets you measure the intensity of magnetic fields via the A1454 Linear Hall Effect Sensor or the TCS40DLR Discrete Hall Switch. This particular version of the A1454 is intended to be used with ferrite type magnets.
Hall Sensor Wirelings ship with a magnet starting February 2020.

TECH SPECS
Allegro A1454 Hall Sensor Specs (Analog)
- 2 factory programmed sensitivity options: 2 LSB/G (for fields up to ±1000 G) and 4 LSB/G (±500 G)
- Temperature-stable sensitivity for NdFeB and ferrite magnets
- I2C interface for easy integration with support for up to 127 unique addresses
- EEPROM stores factory-programmed settings and up to 16 bytes of user information (programmable through the I2C interface)
- Micro-power sleep mode through I2C command for minimizing power in battery-operated applications
- Precise recoverability after temperature cycling
- Wide ambient temperature range: –40°C to 125°C
- 12-bit ADC with 10-bit ENOB (Effective Number of Bits)
- Operating Voltage: 2.65V - 3.5V
- Operating Current: 5mA (max)
Toshiba TCS40 Hall Switch Specs (Digital)
- Omnipolar (dual detection)
- Open-Drain
- ßON = 3.4mT

TinyDuino Power Requirements
- Voltage: 3.0V - 5.5V
Pins Used
- A5/SCL - I²C Serial Clock line
- A4/SDA - I²C Serial Data line
Dimensions
- 10mm x 10mm (.394 inches x .394 inches)

A genuine color IPS display — you're watching the real thing on the world's tiniest television.
Drag your own clips over USB-C. Home movies, memes, a crackling fireplace — anything you like, on loop.
Change the channel and volume with an IR remote small enough to lose in your pocket — but it really works.
It actually plays my old home videos on a screen the size of a stamp. It's my desk's favorite object.
The remote is absurd and I love it. Setup took five minutes and my clips looked crisp on that little screen.
Build quality is unreal for something this small. Feels like a real gadget, not a toy — and it's made here.
Gifted one to my brother and now the whole family wants one. Tiny, but seriously mighty.
Battery lasts through a work day on my shelf and the fireplace loop is weirdly cozy. Zero regrets.
Loading my own videos over USB was dead simple. It's the best desk conversation-starter I own.
