Design Specification 3.1 Processor The board currently uses AM3352 processor in the 15x15 package. Actual processor speed will be determined by the actual devices supplied. The board is being released prior to the processor being in full production and as a result, has the AM3352 due to availability of those parts at this time. 3.2 Memory As single x16 bit 4GB DDR3 memory device is used. A single 32KB EEPROM is provided on I2C0 that holds the board information. This information includes board name, serial number, and revision information. Unused areas can be used by SW applications if desired. 3.3 Power Management The TPS65127C power management device is used along with TL1936A and TPS73618BVR LDOs to provide power to the system. 3. 4.1 Serial Debug Port Serial debug is provided via UART0 on the processor using a dual channel FT2232H USB to serial device from FTDI to connect these signals to the USB port. Serial signals include Tx, Rx, RTS, and CTS. 3.4.2 JTAG Port The second port on the FT2232H will be used for the JTAG port. Direct connection to the processor is made from the FT2232H. 3.5 MicroSD Connector The board is equipped with a single microSD connector to act as the primary boot source for the board. A 4GB microSD card is supplied with each board. The connector will support larger capacity SD cards. 3.6 Power Sources The board can be powered from an optional 5VDC power supply. The power supply is not provided with the board and must be a grounded power supply. 3.7 Reset Button When pressed and released, causes a reset of the board. Due to the small size of the switch, you will not experience a lot of travel when pushing the switch. 3.8 Indicators There are seven LEDs on the board. Four can be controlled by the user and one static LED. One power LED indicates that power is applied. Four blue LEDs that can be controlled via the SW by setting GPIOs. One white LED indicates that WIFI is up. One blue LED next to the white LED indicates that Bluetooth is up. 3.9 WIFI/BT chip The board uses TI WL1835MOD chipset. WIFI: WLAN Baseband Processor and RF Transceiver Support of IEEE Std 802.11b, 802.11g, and 802.11n. 4-bit SDIO Host Interface Support. 20-MHz 2 x 2 MIMO and 20- or 40- MHz SISO Channels for High Throughput: 80 Mbps (TCP), 100 Mbps (UDP). Bluetooth and BLE: Bluetooth 4.0 and CSA2 Support. 4. Product Appearance 5. Interfaces A.
