ITEADMAPLE 72MHz, 39xI/O, 16xanalog USB/3USART/SPI/I2C

Overview

Iteadmaple is a microcontroller board based on Leaf Maple. The Iteadmaple can achieve the maximum 72 MHz, it has 39 digital input/output pins, 16 analog inputs, native full speed USB, 3 USARTs (hardware serial ports), integrated SPI/I2C support, with power jack, and reset button. Iteadmaple is programmable over USB via a provided DFU bootloader, no extra hardware required! Users can also program the onboard program flash via external X-link/X-linkEx JTAG interface. Iteadmaple offers security support for read/write protected addresses, as well as User and Handler processor modes. Iteadmaple can be powered by USB or external power supply.

• 64 channel nested vector interrupt handle
• 7 channels of Direct Memory Access(DMA)
• Wide range external input from and USB supply adaptive
• X-link/X-linkEx full compatible
• Pins map full compatible for Arduino shield

This board is a redesign of the original Maple board (not the Maple RET6) and uses the STM32F103RB microcontroller. 

There should be no need to press the 2 buttons before upload. However I have notice the board seems to need to be reset after upload, using the reset button, otherwise the USB Serial device doesn't get activated.

Use Arduino 1.6.3 IDE with files from my GitHub repository https://github.com/rogerclarkmelbourne/Arduino_STM32/wiki and it works fine.
