Hello,I have developed a custom board based on the MB997E reference design, which uses the EMIF02-USB03F2 for USB EMI filtering and ESD protection. Since this component has been declared obsolete, I would like to know:What is the recommended replacem...
I use STWD100NY Watchdog IC and for now, i can not achieve what i want. The problem is about to get output from the WDO pin. I did not connect the WDO to the MCU but i connect it to drive a relay. I set up my timer to 4 seconds. Even if it exceeds th...
Board name is stm32f103c8t6(blue pill) STM32 Bare-Metal Temperature Sensor with LED IndicationBuilt a bare-metal application on STM32 to read the inbuilt temperature sensor via ADC by directly configuring registers (no HAL). The ADC value is mapped t...
Hi everyone,I am using STM32F103c8t6 module for transmitting and receiving data in between two SX1262 LoRa module. The libraries are found in https://github.com/Lora-net/sx126x_driver/tree/v2.3.2 link and i have successfully transmit and receive data...
Hi everyone: i received in these days a custom PCB i designed based on the STM32F411 microcontroller:I wanted to experiment with such MCUs and make a custom board with them for the first time; i was also interested in making it compatible with the ar...
Hi,We are currently looking for a power metering IC. We are thinking of using the STPM32 for this purpose.In our device we can only switch on and off the line to our load. The Neutral of the load is not passing through our device. It is connected to ...
hi i need help how to read date code for VND05BSP attached picture thanks
https://controllerstech.com/stm32-usb-host-msc/I downloaded the app from this site, and the project from 2020 works. However, even though I followed the same tutorial, my code doesn't work in the 2025 version.
Hey folks, I’m new to PCB design and I ran into something odd. I had a small board made for a project, but during testing some of the traces get warm and one even browned slightly. I thought I sized them correctly in KiCad, but maybe I messed up.Do P...
Hi,I’m looking for the ECCN (Export Control Classification Number) for this part:Part number: NAND01GW3B2BN6EDescription: 1 Gbit NAND Flash, industrial temperature, TSOP48 packageSome distributors say it’s EAR99, but based on the specs (over 16 Mbit ...
