2pcs GY 471 3A Range Current Sensor Module MAX471

【GY471】 This module can be used to test the current and voltage. The power chip on the motherboard is used to test the load current consumption. 【Design compact】 The principle of the voltage test based on the design principle of the resistive voltage divider, can make the input voltage of the red terminal connector 5 times smaller. Analog input voltages up to 5 v, input voltage of the voltage detection module no greater than 5Vx5 = 25V (if 3.3V systems are used, input voltage not higher than 3.3Vx5 = 16.5V). 【High performance】 AVR chips have 10-bit AD, so this module simulates a resolution of 0.00489V (5V / 1023), so the minimum voltage of the input voltage detection module is 0.00489 Vx5 = 0.02445V . 【Fast delivery】 Fast and high quality delivery of Spain buying in TECNOIOT
