HW-CAN: A Highly integrated USB-CAN Sniffer based on STM32

by

I had been looking for this kind of products for a long time without so many good results (maybe I’m not so good in searching :P). Tha main key-features that I was looking for were: Being based on STM32, that is where I have more experience and I can customize and develop my own firmware. … Read more

HW-MODS: A prototype board for the STLINK-V3-MODS

by

Since STMicroelectronics presented it, I had been very curious to try it. There where all the specs for being a very usefull thing: a cheap and really small debugger intended to be integrated on every custom PCB that needs onboard debugging capabilities. I have immediatly decided to develop my own PCB in order to get … Read more

Say welcome to the OpenDAQ

by

An open source data acquisition board based on the STM32F4.
Features:
-10x extremely high resolution analog inputs (32bit primary ADC+ 24bit secondary ADC)
-4x low res analog inputs (12 bit embedded ADC)
-4x NPN logic isolated digital output
-2x programmable analog outputs (12bit DAC + op-amps)
-PC connections available over USB or wifi (nrf24 or esp8266)
-2x I2C interface
-4x UART/USART interface
-1x SPI interface (shared with nrf24)
-Expansion GPIO for extra CAN, digital inputs/outputs, 3v3 regulated power supply, usart, i2c connections
-Wide operating input voltage: from 6,5 to 36 Volt

Additionally to the STM32F4 you can use an ESP8266 to develop custom Wi-Fi application. It is interfaced with the micro by uart.

More information about price, availability and a getting started guide will be made available soon..
