From Zeros to Heroes, One Bit at a Time.
Lonely Binary is a small Australian electronics company in Macquarie Park, Sydney. We design our own development boards and modules: the ESP32 and ESP32-S3 Gold Edition boards, the PinPulse shields that put an LED on every GPIO, and TinkerBlock, the plug-in sensor and display blocks that let a first project start without a soldering iron.
We write the manual too
Every board we make has a handbook on Lonely Binary Learn: wiring, example code for Arduino and MicroPython, and a 3D model of the real board you can turn over. Scan the QR code on the box and you land on your product's page. When you want to put a project on a dashboard, Fluxgrid does it in a few lines of code, free.
Talk to the people who made it
Questions go to the team that designed the board, not a call centre. Email office@lonelybinary.com and we'll reply within 24 hours on business days.
