Are there 2.5V ibis models available for the 54VCXH162245? I was only able to find a 3.3V model on the website. Thanks, Jose

BLUENRG-M2SP PCB antenna vs chip antenna

Hi,I would like to evaluate the BLUENRG-M2SP module, but I have a question: Does the PCB antenna on this module have a disadvantage over your chip antenna module which is the SPBTLE-RF module? Actually since this is a new design I tend to use already...

SPIRIT1 link budget

Good afternoon,I'm developing a low power radio stack based on SPIRIT1. I encountered a strange behavior in the radio, using the SPIRIT1_Library from ST. I positioned two board within 5cm between each other and using the function "SpiritQiGetRssi" I ...

For STEVAL-IDP003V1 module I've acquired for IO-LINK communication with STEVAL-IDP004V2 master module... Where can I find the HEX file to download on the SLAVE SENSOR? Is it included in the STEVAL-IDP004V2 package? Please tell me soon. Thank you.

1. When using the SD interface of stid135 demodulation chip, we found that MCLK output driver is insufficient. We connect the data line of the SD and MCLK directly to the IO of the FPGA, and the FPGA grabs it online, so we can't get it? Can you solve this

How to switch between Low power modes of a BLUENRG2-M2 BLE module ?

I am using BLUENRG-M2 module as a Network Processor (Controller) and an STM32L4 MCU as a host. I want to make the device connectable via Bluetooth during a limited time (e.g 30 seconds) then put the Controller to SLEEP mode (e.g 30 seconds) to save e...

STUSB4700 GUI offline

The STUSB4700 GUI (STSW-STUSB001 v3.23) requires to be connected to the STM32 Nucleo board + STUSB4700 to be able to start.So if you don’t have a Nucleo board, or if you didn’t wired the I2C interface of STUSB4700 to a Nucleo board, then you cannot u...

How to connect STUSB4700/4710 GPIO pins to a DC-DC feedback path

I'm currently designing a source solution for PD up to 20V 5A. I have the STEVAL-ISC004V1 board for the STUSB4710 and noticed in the schematic that the feedback ladder is connected directly to the GPIO pins on the STUSB4710. The ISC003V1 board howeve...
