The idea

Already part of the sim racing scene, JohnJohn 3D began expanding its product range and working with partners on solutions the community wanted. An old request came up: a load cell. It wasn't new to the market, but as always, we like to innovate!

Unlike many models on the market, the LoadCell JJLC-01 doesn't just send braking force to your PC through extra wiring. It integrates with Logitech G Series pedals, so your wheel and pedals believe they are using the original potentiometer, while under the hood the JJLC-01 is working to give your feet the best.

Dynamic software configuration

With JJManager you can easily configure your JJLC-01, the same way well-known pedals on the market work. Want 20% braking at 5 kg, 30% at 10 kg and 40% at 25 kg? You can!

Built-in EEPROM

In plain English, an EEPROM keeps data saved even without any power. So you can configure the LoadCell JJLC-01 and then unplug its USB cable from the computer, because all settings stay stored on its own circuit. Fewer cables while driving, fewer problems!

Load cell rated up to 100 kg

Among the technologies inside the JJLC-01, we can't forget the load cell itself: it handles up to 100 kg of force, giving you more precise tuning while using the JJLC-01.

Built to last

Because the parts are 3D printed, many people worry they will break easily. Here at JohnJohn 3D we tune our print settings so our products are as strong as possible!
