MYIR announced a Linux- and Android-ready COM called the “MYC-AM335X” with six versions of the TI Sitara AM335x SoC, plus a baseboard and touchscreens.

Shenzhen-based MYIR, which recently released a series of low-cost MYC-SAM9X5-V2 computer-on-modules (COMs) based on Atmel’s AT91SAM9X5 system-on-chips, is now taking pre-orders for two versions of a new TI Sitara-based MYC-AM335X COM. Like its Atmel-based cousins, MYIR’s low-end MYC-AM3352 and high-end MYC-AM3359 are each available for $68.

The two available MYC-AM335X COMs, which are equipped with the Texas Instruments Sitara AM3352 and AM3359, respectively, are the only modules that can be bought in single-unit quantities. Modules based on the other four pin-compatible SoCs — the AM3354. AM3356, AM3357, and AM3358 — are offered only as “mass quantity” purchases, says MYIR.

Also up for pre-sale is MYIR’s $139 MYD-AM335x development board, and 7-inch ($99) and 4.3-inch ($60) LCD touchscreens. All the products are aimed at industrial embedded applications such as automotive, control systems, lighting, refining, and processing.

 
About TI’s Sitara AM335x

The 720MHz, Cortex-A8-based Sitara AM335x has been one of TI’s most popular embedded SoCs over the last year, appearing in numerous COMs such as ISEE’s recent IGEP Aquila. The AM3359 also fires up the BeagleBone Black SBC.

The AM3359, AM3358, and AM3354 are the only models with a PowerVR SGX 530 3D graphics accelerator. The AM3352 is the only one that lacks a GPU of any kind, and unlike the AM3359, there’s no PRU-ICSS (Programmable Real-Time Unit and Industrial Communication Subsystem). The PRU-ICSS comprises dual 32-bit RISC microcontrollers that enable customization of I/O, including EtherCAT, PROFIBUS, PROFINET, and EtherNet/IP-based interfaces.

 
MYC-AM335X details

MYIR’s MYC-AM335X modules measure 70 by 50mm, and feature a pair of 2.0mm pitch, 60-pin male expansion connectors that carry all I/O signals to a baseboard. There are also two other expansion interfaces with reserved solder joints, “which have extended a few signals for some special purpose,” says MYIR. These include a 2.0mm pitch 26-pin interface and a 2.54mm pitch 10-pin interface.

The MYC-AM335X COMs are equipped with 512MB DDR3 SDRAM and 512MB NAND flash, as well as an onboard gigabit Ethernet PHY. I/O includes dual USB 2.0 OTG ports, six serial ports, three SDIO interfaces, and various industrial I/O.

The modules ship standard with commercial temperature ranges, but industrial -40 to 85°C versions are available, as well. Linux, Android, and WinCE BSPs are also provided.

MYIR offers a MYD-AM335X development board for the MYC-AM335X, as well as a pair of LCD options. The 130 x 100mm baseboard is equipped with a microSD slot and two gigabit Ethernet ports. Other coastline ports include dual serial ports, with one designated for debug, plus two USB 2.0 host ports, and a mini-USB 2.0 OTG port. There are also real-world HDMI and audio ports. Onboard interfaces include CAN, RS485, and LCD with touch support.

The board’s touchscreen options include the 7-inch, 800 x 400-pixel MY-LCD70TP and the 4.3-inch MY-LCD43TP, which offers 480 x 272 resolution. Both models include an LCD adapter board and a 50-pin interface cable.
