Page 6: Target Market Of The Board
AM3352-SOM user's manual 1.2 Target market of the board Using the AM3352-SOM as a stand-alone development board would be more suitable for users with some hardware experience or people already familiar with other single-board Linux boards and designs. As mentioned in the previous chapter the board is meant to be implemented in a hardware design. -
Page 7: Board Variants
OLIMEX© 2015 AM3352-SOM user's manual 1.4 Board variants At the time of writing this document, AM3352-SOM is the only Olimex-made board featuring Texas Instruments AM3352. Other SOM boards that might be compared to functionality are: the well-supported A20-SOM, and the new powerhouse RK3188-SOM. -

Page 10: Chapter 3: Setting Up The Am3352-Som Board
3.1 Electrostatic and electrical polarity warnings AM3352-SOM boards are shipped in a protective anti-static package. The board must not be exposed to high electrostatic potentials. A grounding strap or similar protective device should be worn when handling the board. Avoid touching the component pins or any other metallic element. -
Page 11: Requirements
AM3352-SOM user's manual 3.2 Requirements In order to set up the AM3352-SOM board optimally one or more additional items may be needed. These might be generally placed in two categories: Required – items that are needed in order to achieve minimum functionality;... -
Page 12: Powering The Board
3.3.1 Stand-alone powering If you use the board in stand-alone mode (e.g. it is neither attached to AM3352-SOM-EVB nor to any other board of peripherals) there are fewer options for powering it. Consider that you might need additional cables or connectors. You have the following options of powering the board: 1. -

SOM-EVB, but what are the requirements to power AM3352-SOM-EVB? You need to provide 6V to 16V DC voltage to the power jack (named PWR) of AM3352-SOM- EVB board. The DC barrel jack has 2.0mm inner pin and 6.3mm hole. More information about the exact component might be found here: https://www.olimex.com/wiki/PWRJACK... -
Page 14: Interacting With The Board
AM3352-SOM user's manual 3.5 Interacting with the board The typical and recommended way of interacting with AM3352-SOM board is via a serial cable connected between the UART0 header and a personal computer. You would probably need a cable suitable for such a connection due to the fact that most personal computers lack a serial port nowadays. -

However, there is only a 40-pin female connector AM_CON-LCD with a 0.05'' step. Unlike other OLIMEX Linux-enabled boards, the AM3352-SOM lacks a row of pins that allows the user to connect a display out-of-the-box. The board's AM_CON-LCD connector is female and has a smaller 0.05'' step (note that if you are using AM3352-SOM mounted on AM3352-SOM-EVB a... -

24 MHz quartz crystal Q2 is found at balls V11 and V10 of the AM3352 processor. 5.3 Power supply circuit A stand-alone AM3352-SOM consumes around 0.10A when connected to a 5V voltage source (provided at UART0 pins “GND” and “+5V”). -
Page 21: Chapter 6: Connectors And Pinout
The pins of the UART0 header might be used for serial communication between the board and a personal computer. They can also be used to power the whole AM3352-SOM board. In the case of a video output problem a cable might provide the needed feedback and greatly reduce the efforts needed to repair the board or to adjust the software setting. -
Page 22: Microsd Card Connector
OLIMEX© 2015 AM3352-SOM user's manual The UART0 header can also be used to power a stand-alone AM3352-SOM. This is the recommended way of powering a standalone AM3352 board. The voltage input pin (+) is named “+5V” and it is suitable for 5V DC external power supply unit. One of the two GND pins can be used as ground (-). -
