A few months ago, I wrote about low cost logic analyzers selling for $75 and up, but yesterday, I stumbled upon an even cheaper, and admittedly lower end, logic analyzer called USB123 USBee AX PRO, allegedly a clone of the original USBee AX PRO minus the analog inputs, that sells for $9.99 on Dealextreme. [Update: It can also be bought for $5.60 on Aliexpress including shipping to most countries]
- Sampling rate – 24Msps
- Sample rate – 24MHz @ 8 channels
- Input voltage range: 0~5V
- Digital channel: 8
- Low input voltage: < 0.8V; High input voltage: >1.4V
- Supported Protocols – SPI, IIC, UART, SMBus, I2S, CAN, Parallel, Custom, Search, Async, 1-Wite, PS/2
- Dimensions – 5.4 cm x 2.7 cm x 1.8 cm
- Weight – 60 grams
The tool ships with 10 Dupont cables and a USB cable to transfer data to your PC. DealExtreme also provides CDROM image with a user’s manual and utilities such as USBee program and a key generator… But many users report either that the program does not work, or it’s difficult to setup, requires changing the PID/VID, and so on. DX first listed the device in 2012, and it’s become relatively popular, with one person writing a review that year.
Luckily you don’t have to use (cracked) proprietary software as USBee AX PRO mini logic analyzer is compatible with Sigrok, and users’ feedback is that it work in Windows and Linux both with the command line and PulseView graphical user interface.
