IO Expander Breakout

Pimoroni

£4.55

Add oodles of extra analog-friendly input and output pins to your Raspberry Pi (or Raspberry Pi Pico) project! This breakout uses a clever Nuvoton MS51 microcontroller and some I2C magic to give you a whopping 14 additional input/output pins to connect things up to. Eight of the pins are hooked up to an Analog to Digital Converter so you can easily use old skool analog sensors with your Raspberry Pi, as well as passive components that use an analog signal (like light dependent resistors). Six of the pins can be used as (up to 16-bit) PWM outputs - great for controlling devices that require a s

Where this comes from

The part other shops don't tell you. Three separate questions, kept separate on purpose, each with its source.

UK company
Registered at Companies House as PIMORONI LTD, number 07510759. Checked 2026-08-29.
Means the business is a British legal entity, not a British-sounding name owned elsewhere. It says nothing about where anything is made.
UK operations
Stated by the company: "moving into our (hopefully) forever home at Parkway Drive - our first building with a roof that didn't leak" — names a location but no site or process, so this corroborates uk_hq more than operations. Source.
Means people employed here, or premises they actually work from. We keep this separate from the company badge because a registered office can be an accountant's spare room, and a company can be registered in Britain while everything it does happens somewhere else. Where we have not looked, we say so rather than assuming.
British-owned
No majority shareholding traced outside the UK. Companies House.
Read from the register of people with significant control, following the chain of holding companies. It does not gate anything: a firm can be made here and owned elsewhere, and that is worth telling you rather than hiding.
Where it is made
The maker doesn't say, so neither do we.
This is about the individual product, not the company. A British firm can sell things made abroad, which is normal and not a criticism. We would rather tell you which is which than average them into a score.
