PLT-300A: The new standard in factory programming and test automation.

Production Line Tool

Programmable Power Supply
1.8V, 3.3V, 5V, variable up to 24V to your device under test.

Secure Connection
Encrypted connection between production line and your backend via PLTcloud.

Program Linux & 32 Bit Devices
Use JTAG, SWD, UART, USB or directly flash microSD cards, verified support for loads of MCU targets.

Aircraft-Grade Aluminum
Tough, lightweight, and highly recyclable enclosure.

Digital Multimeter (DMM)
Measure voltage current, resistance, and capacitance with code.

Hardened Linux
PLT-OS is purpose built for the production line.


Manufacturing is not easy and we designed the PLT-300A to be intuitive for the line manager setting it up and the operator using it, wherever they may be on the planet. Our efforts were recognized with a product design award from iF.


The PLT-300A is certified by the ioXt Alliance, a global device-level certification created by industry leaders to improve the security of IoT hardware.


Through our support of Climate Neutral we measure, reduce, and offset all carbon emitted to make PLTs and maintain the PLTcloud backend. We are working hard to reduce the environmental cost of all electronic devices with the 10 ways outlined in our Better Devices Manifesto. The PLT-300A relieves pressure to send engineers to distant production site for setup and troubleshooting.
