    I'm developing a gateway station that receives data over RF from sensor-stations, and send this data to a cloud via WiFi. I need to do 2 improvements to it. On one hand, I need to control a wifi modem. turn it on and off every time the the GW sends new data to the cloud. On the other, I'm using the LM2596 as voltage regulator. It goes from the 12V supplied by a solar panel to stable 5 volts, this supplies the wifi modem and other route goes to a LDO-3.3V. I don't want to use the module () anymore and embed it to the PCB as a fixed-5V circuit. So i Ask for: 1. Add a transistor circuit to supply 5V to the modem (from the lm2596 regulator) when the ESP32's GPIO commands. Add it to the

    ...circuit board that incorporates a TI INA229 current and voltage sensing IC, along with a PCB mounted shunt resistor capable of handling up to 50 amps. The board should be designed to withstand industrial use. Key Requirements: - Incorporating TI INA229 current and voltage sensing IC - Capable of handling up to 50 amps, 85V DC. - High durability for industrial use - All external connections to be via screw terminals (e.g. phoenix) and support the required current. - calculation of required parameters for INA229 register settings. - Size is flexible - Would be ideal if there was onboard 5V regulator for VIN of INA229, but open to this being external supply. Ideal Skills: - Strong background in PCB design - Experience with current and voltage sensing ICs - Knowledge ...

    ...of the water pump. This comprises of 12DC input from a constant voltage (12v, 30W) plug and IRF520 MOSFET module for control of the water pump. The Arduino output and ground pin are connected to the MOSFET in order to control the pump. However, I am stuck on how to integrate the LED grow strip into this circuit. Does anyone have any suggestions on how I can power and wire up this circuit to facilitate both the grow light and pump (the simpler the better)? In addition, any suggestions for the type of MOSFETs I could use to control the LED would be very welcome. To make things a more complicated, it is suggested that LED grow strips receives constant current, so temperature changes in the LEDs don’t cause an increase in voltage over each LED. But, this may not be an is...

    Trophy icon Power Management Circuit Optimisation Finalizado left

    I'm in need of a skilled electronics engineer with experience in power management circuits. Your task is to optimise a battery protection sub-circuit that is already working but uses too much power. The circuit is used to protect a lipo battery from overvoltage, if the charging voltage goes above 4.2V then the battery should be disconnected until the voltage drops below 4.2V. The existing circuit operates by using a comparator to compare a reference voltage to the battery voltage and using a PMOS switch to disconnect if required. There are a number of key criteria that must be achieved and are non-negotiable. - The passive current of the total circuit should be as small as possible <50uA, currently over 1mA - The design needs to be triplicated (see s...
