Ina219 shunt resistor value
WitrynaThe chips monitor both a shunt voltage drop and bus supply voltage. +INA260 is a high or low side current and power monitor with an integrated +shunt and I2C interface. + The shunt value in micro-ohms can be set via platform data or device tree at compile-time or via the shunt_resistor attribute in sysfs at run-time. Please refer to the ... WitrynaI also bought the INA219 but I read that as far as precision is concerned, the IN222 is better, so I bought that too. The use of this module is for a design of a bench power …
Ina219 shunt resistor value
Did you know?
WitrynaA large value resistor will develop a larger differential voltage as the current passes through. The measurement errors will be smaller due to the fixed amplifier offset voltage. However, the larger signal creates a larger power dissipation across the shunt resistor (P = I2R). A smaller shunt resistor develops a smaller drop across the shunt ... Witryna27 wrz 2016 · You have a 12V power supply so we stick with the 16V of the example (you can choose between 16V and 32V) The shunt resistor value is 0.1 Ohms for the Adafruit board. Your actuator draws 5A at max load. Ohms law tells us that max …
