Arduino Pro Mini 328 Mini ATMEGA328 3.3V/16MHz

Using Atmel Atmega328P - AU microcontroller digital input/output port RX and TX, D2 ~ D13, A0 ~ A5 8 analog input port A0 ~ A7 Support serial download 16 MHZ clock frequency

Add two rows of the holes for the pins. So it can be connected with normal Dubond line. Add 3 rows of the holes for wiring. Change the in-line package of ATMEGA328P to flat package. CH340G Replace ATmega16U2

STM32F030F4P6 ARM CORTEX-M0 Core Minimum System Dev Board for Arduino Model: STM32F030F4P6 16K flash memory, 4K SRAM. The target MCU is STM32F030F4P6. This board is a STM32F030F4P6 Minimum System Board (Cortex-M0) It's a ARM 32-bit Cortex-M0 CPU, frequency up to 48 MHz, high-speed embedded memories. Integrating micor USB power supply interface. ISP/SWD programming/debugging interface, boot mode selection and more feature rich device. Color: blue

The development board using MicroUSB cable supply, compatible with smart phone lines, data lines is simple and easy to get, but not USB MINI line-powered, USB MINI line is not easy to find, has been gradually phased out. Other manufacturers of products are used in MINI-USB port, this is not applicable for customers. Low price, user-friendly design, a full set of data, allowing you to save money, save time, effort, worry! STM8S core board of the main features: 1. Use STM8S103F3P6 as the master IC. 2. You can use 2.54 pin on the board or power supply pad, the pad when using power supply, input voltage range 4.5V-15V, can output to the outside through pin 3.3V! Note: 5V pin?s voltage is the input voltage of the module. 3. leads to all pins, the pins next to the pin marked the label, with a reset button, power LED, and the program demonstrates LED, small but perfectly formed. 4. Support SWIM debug mode. 1. The core board schematics (PDF format) and tested source. Burned into the test program, LED flashes, allowing you to detect the core board is working properly. 2. Provide at IAR and STVD two development environments register operation and routine operation of the library functions. Timer routine, UART transmit routine, UART receive routines, clock switching routines, AD routines and so on. 3.STM8 Applications. 4.STM8 package library. 5.IAR development environment, STVP programming software.
