S2-LP: SMPS maximum output current
Hi,I would like to know what is maximum output current of the SMPS. I want to optimize my BOM cost and planning to take advantage of this voltage regulator. Obviously it is a low power circuit.
Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.

Hello. I am making RF beacon based on SPIRIT1 RF ICI downloaded SPIRIT1 DK, configured for 168MHz based on hardware I have, and written CW mode. But with spectrum analyzer with sweep from DC to 1GHz i can't see anything ( same goes if i select 169MHz...
Hello,We are a startup from Surat,Gujarat.https://vegg.co.in.We are developing our next gen products based on PLC with smart homeWe are using ST8500 in that projects.The problem that we are facing using that ic,If you can provide us some info it will...
Are these modules share the same stack? If I whant to use both in my project - should I include a ble_core folder only from one of them?
I am using an SPBTLE-RF0 and I am having issues writing data more than 72 bytes to a write-only characteristic. I setup the characteristic as follows: ret = aci_gatt_add_char(serviceHandle, UUID_TYPE_128, uuid, 128, CHAR_PROP_WRITE, ...
We are having strange problems with some of our products that use the M41T83. I'd like to try forcing an oscillator fail in order to see how our product behaves. Is there any way to do this? I tried writing to the Flags register (0x0F) but the values...
Hello, I am having some trouble with getting I2C to work.My code:void i2c_init(void) { /* Periph clock enable */ SysCtrl_PeripheralClockCmd(CLOCK_PERIPH_GPIO | CLOCK_PERIPH_I2C2, ENABLE); // I2C2 pins GPIO_InitI2c2ClkPin4(); // SCL at DIO4 ...
Hello, I am experiencing problems with using ADC together with BLE. When I comment out BTLE_StackTick() inside main loop, the ADC reads values correctly (checked over UART). But when BTLE_StackTick() is called, ADC always returns 0.6V. What is the so...
I am using an STEVAL-IDB008V2 board which contains a BlueNRG-2 chip. I am testing out this product using Keil uVision (version 5.29.0.0), and I am running the BlueNRG-2 sensor demo code (with sleep function removed; I learned this causes problems).T...
We produced a 4 channels RS232 to 485/422 converters using a FTDI4232 and four ST485BDR. When apply the 120 Ohm load resistor, some ST485BDR send the pin 1 to low state, lighting the RX LED.When the pin 1 goes low, the RX LED remain lite. If I touch ...
