Talk to boards, modules and microcontrollers over UART, SPI and I²C — plus 8 general-purpose I/O lines to read and drive.
Program and debug microcontrollers directly — full TCK/TDI/TDO/TMS and SWDIO/SWCLK lines on the debug header.
ONITRON senses the target's voltage — 1.8, 3.3 or 5 V — and level-shifts every line automatically. Connect without frying anything.
Protected 3.3 V or 5 V output to bring a dead board to life and inspect it — no bench supply needed.
Read and write 13.56 MHz tags and cards — inventory, access badges, MIFARE and friends.
Receive, record and analyse 315/433/868 MHz signals — remotes, sensors, telemetry. Built for legitimate diagnostics.
ONITRON acts as the USB master: plug in keyboards, drives and devices and interrogate them — with overcurrent protection.
Save captures, dumps and logs straight to microSD. An RGB status LED tells you what's happening at a glance.
Connect over USB-C. The interface runs on Web Serial / WebUSB, straight in the browser.
ONITRON creates its own WiFi network and serves the interface itself. No cable, no app, no App Store.
Zero installation · Zero drivers · Zero apps — just a web page
The swiss-army knife for technicians, developers and repairers. One pocket tool that replaces the serial adapter, the JTAG programmer, the bench supply, the NFC reader, the RF analyser and the USB host — driven from any browser, iPhone included.
