Hi, I have to interface microcontroller with ST4SIM-200s through modem for cellular connectivity. But I can't find out any details about modem from data brief of ST4SIM-200s. can you give me suggestion about modem?
I am looking at using the STUSB4710 in a specific application where when the device is installed, it can be configured to support different maximum power output levels. So I really have a few questions.Q1. The data sheet says "The STUSB4710 has a set...
I am currently working on a PCB for a low energy Bluetooth application and we decided to use the BlueNRG-332ac QFN32 package.Now I want to know if there is any difference between the BlueNRG-LPS and BlueNRG-332ac.Also I am looking for a BOM for the s...
Dear ST Community Support,We are currently evaluating the ST4SIM-200M eSIM module for integration into our IoT devices and would like to clarify some details regarding its activation and compatibility.Specifically, we would like to confirm whether th...
When looking at the datasheet for the ST67W611M1, it seems that pins CHIP_EN, SPI_CS, and SPI_RDY are all High active. Is this really correct, or are some signals simply missing the bar on top? Also, the description for pin BOOT doesn't indicate whi...
Hi Team, Do you support USB type C PD 3.1 supporting 240W for sink applicat? If yes, please suggest a suitable part number with the datasheet. If you do not support 240W, please let us know the maximum power supported by STM for USBPD 3.1 application...
Hello everyone.I'm currently building a controller for this energy measurement chip.So far, I've built my controller and can perform a remote reset and read data, but when I want to configure a register, I send my desired configuration, but when I re...
Hello, I am using STPM34 smart metering chip to read 230 VAC voltages and currents. I am using 3 chips on 1 board:First 2 STPM34 measure 3 phases of 230 VAC voltages and currents, 3 STPM34 measures 16 multiplexed current channels and no voltage.I am ...
Hello,Could you please provide a simple example source code to operate an S2-LP transceiver under the following conditions? My MCU is an STM32F103 connected via SPI1.A 25 MHz crystal is fitted to the S2-LP.External SMPS (1.8 V) is used.I want to tran...
Hello everyone, I’m trying to control an S2-LP QTR via SPI1 on an STM32F103VCT. I completed the initial setup and configured the radio to 420 MHz. I then wrote a routine to transmit periodically, but I’m not seeing any RF output on the antenn...
