1.2 H407 or E407?

The major difference between STM32-H407 and STM32-E407 is that the latter has built-in
Ethernet (physical level transceiver Microchip's LAN8710A-EZC). STM32-E407 also features an
extra USB-OTG and a number of SMD jumpers on the bottom which help the user to control the
multiplexing on some pins easier. STM32-E407 has 2 x USB-OTG both with a miniUSB interface.
STM32-H407 has 1x USB-OTG and 1x USB-HOST with the On-The-Go interfaced by miniUSB
and the HOST by USB type A connector.
If you need built-in Ethernet check the STM32-E407.

1.3 Target market and purpose of the board

STM32-H407 is a development board featuring a powerful ARM Cortex-M4F microcontroller with
the most important peripherals, interfaces and connectors mounted and ready to use. The board can
be powered by a number of different sources, can be programmed via two different interfaces, has a
TON of GPIO pins available on a number of headers. The board's Arduino platform headers give
another option for enthusiasts who wish to implement support for Arduino/Maple/Pinguino shields
giving the board additional features altogether with the option to add Olimex extension modules on
the OLIMEX UEXT.
The board can be programmed via Arduino IDE using USB_HOST connector.
All of the above options make the board quite versatile and suitable for numerous tasks and
situations. The power of ARM and the creativity of OLIMEX come at the best price and the well-
known quality.
Every ARM enthusiast would see STM32-H407 as an interesting bargain and quite capable board
for its low price.
