Mini Pro ATmega328P CH340G 5V Development Board Compatible with Arduino IDE

The board is based on ATmega328P, made entirely with SMD (surface mounted) parts.   This is intended for users who require flexibility, low-cost, and small size. It comes with the minimum of components (no on-board USB or pin headers) to keep the cost down. It's a good choice for a board you want to leave embedded in a project.   This is a great development board to miniaturize your project, bring the cost down and allow for customized connectors.   This is a great budget purchase!   You will need an USB to UART TTL Module to program your board; only one Module will program as many boards as needed.       Technical Specs:   Controller：   ATmega328P   Input Voltage：   5V   Digital IO pins ：   14 (of which 6 provide PWM output)   Analog input pins ：   8   DC Current per I/O Pin：   40 mA   EEPROM：   512 bytes   SRAM：   1KB   Operating voltage:   5V   Clock Speed:   16 MHz   PWM channel:   6
