Review on 🔧 HiLetgo PRO Mini Atmega328P-AU 5V/16MHz Development Board with Bootloadered Microcontroller and Pin Headers – Pack of 3 by Matthew Goyette

They work well but I have a few problems. First, as other reviews have noted, the pinout of the FTDI programming is different than the amino version. It's not a big problem, but you should pay attention to it. Second; I have these boards for low power applications, the series resistors with the LEDs are 1k ohms, not the Arduino's 10k ohms. This greatly increases the power consumption of the board. Three; The board is said to have a jumper to isolate the voltage regulator and power LED from the board to allow battery powered applications to use less power. On this board you need to remove the components. The board works.
