ATSAM2S4BA Prototype Board, RS232, USB, SD, Pot, Thermistor US$35.61

SAM3-P256
ATSAM2S4BA Prototype Board, RS232, USB, SD, Pot, Thermistor


The SAM3-P256 is a development and prototyping board with an Atmel ATSAM2S4BA-AU microcontroller. The board has JTAG, UEXT, USB and two RS232 connectors, power jack, potentiometer, two user buttons, two status LEDs, power-on LED, reset button and a prototype area for all of the microcontroller's ports.

Atmel's ATSAM3S4BA is a member of a series of Flash microcontrollers based on the high-performance 32-bit ARM Cortex-M3 RISC processor. It operates at a maximum speed of 64 MHz and features 256 Kbyte Flash and 48 Kbyte SRAM, Full-Speed USB Device port with embedded transceiver, a High-Speed MCI for SDIO/SD/MMC, an External Bus Interface featuring a Static Memory Controller providing connection to SRAM, PSRAM, NOR Flash and NAND Flash, 2x USARTs, 2x UARTs, 2x TWIs, 3x SPI, an I2S, as well as a PWM timer, 6x general-purpose 16-bit timers, an RTC, an ADC, a 12-bit DAC and an analog comparator.

This board can be powered 6V DC via a power jack or 5V via USB. Its power consumption with all peripherals enabled is about 100mA.

Using SAM-BA software, the ATSAM3S4BA-AU on this board can be programmed via COM port (with external power supply only), or via USB port (with USB power supply only). Before being able to use SAM-BA, a recovery procedure, which consists of copying the SAM-BA Boot Assistant into Flash, must be performed. See the user manual (available to download below) for instructions.
