Binho Atira
More than just an SWD/JTAG debug probe, the Binho Atira puts the target embedded system under software control, from programmable downstream power with real-time voltage/current/power monitoring to an enhanced serial console, and built-in level shifting across 1.2 to 5.0 V.
The Binho Atira is an all-in-one development tool for modern embedded developers. It debugs over SWD, JTAG, SWO, and RTT, programs SPI flash and EEPROM at up to 24 MHz, and bridges an enhanced UART console, with integrated level shifting and configurable downstream power featuring real-time voltage, current, and power monitoring. Together these enable highly-productive workflows legacy tools cannot facilitate, and automated test and coding agents can drive Atira on their own, so teams ship better hardware, faster.
Atira connects with our Mission Control desktop GUI software for a point-and-click experience and is fully supported by our CosmicSDK for integrations with Python, C/C#/C++, and Java, all fully cross-platform for Windows, macOS, and Linux. The device comes with a modern USB Type-C connector and 5× RGB LEDs for visual status indication, all in a compact, machined-aluminum enclosure with integrated mounting holes.
// highlight
A probe for modern workflows.
From interactive debugging to automated test to agentic diagnostics, Atira fits every stage of modern development, from benchtop bring-up to mass production.
// debug
Debug any Arm Cortex-M.
SWD and JTAG with SWO trace and Real-Time Transfer (RTT), so stepping through code, watching live variables, and capturing event streams all run from Atira.
// program
Flash in seconds.
Program on-chip flash over SWD and JTAG, plus external SPI flash and EEPROM at up to 24 MHz, with read, write, verify, and erase.
// power
Power under software control.
A programmable 1.2 to 5.0 V supply feeds the target and power-cycles it on command, so bring-up and CI reset the hardware without reaching for a cable.
// measure
Real-time power insight.
Live voltage, current, and power on the target supply, streamed during debug, to show exactly what the firmware draws.
// level shift
Matches any logic level.
Bidirectional level shifting from 1.2 to 5.0 V on every line, so a modern low-voltage part wires straight to the probe with nothing extra on the bench.
// observe
An observable console.
Atira shows up as two virtual COM ports: one drives the target, one is a read-only tap that mirrors the traffic, so scripts and coding agents can observe every byte for diagnostics and reverse engineering.
// interfaces
A complete interface to the target.
From debug and trace to programming, serial, and a measured power rail, Atira covers the full connection to the hardware.
