Comparison with Standard Pro Mini

Unlike standard market versions, the WAVGAT Improved Version features a high-stability voltage regulator and optimized trace routing to reduce electromagnetic interference (EMI). It maintains 100% pin compatibility with the original SparkFun layout but offers better heat dissipation and signal integrity for industrial-grade applications.

Frequently Asked Questions (FAQ)

1. How do I program this board? Since it lacks a USB port, you need an external USB-to-TTL adapter (like FT232RL or CP2102) connected to the DTR, RXD, TXD, VCC, and GND pins.
2. Can I power it with a 9V battery? Yes, connect the positive terminal to the RAW pin and negative to GND. Do not use the VCC pin for anything higher than 5V.
3. Is it compatible with Arduino Uno code? Absolutely. In the Arduino IDE, select “Arduino Pro or Pro Mini” and processor “ATmega328P (5V, 16 MHz)”.
4. What is the difference between VCC and RAW? RAW is the input for the onboard regulator (5-12V), while VCC is the regulated 5V output/input.
5. Are the headers pre-soldered? No, they come loose to allow for flexible mounting options (like soldering wires directly or using custom headers).
