TQMa65xx Embedded Module Features TI Sitara AM65xx SoC, Six TSN Ethernet Interfaces

Texas Instruments Sitara AM654 Cortex-A53/R5 SoC was launched in 2018 as the first 64-bit processor from the company and specifically targetting Gigabit industrial Ethernet networks with support for Time-Sensitive Networking (TSN). Since the processor launch, we’ve seen a couple of Sitara AM65xx modules such as PHYTEC phyCORE-AM65x SoM and Mistral AM65x Industrial SOM. There’s now another option with TQ Embedded TQMa65xx embedded module featuring a choice of 5 AM65xx dual-/quad-core processor, up to 4GB RAM, up to 64GB eMMC flash, and various I/Os via a 560-pin connector that includes six Gigabit TSN Ethernet interfaces. TQ Embedded TQMa65xx embedded module specifications: SoC – Texas Instruments Sitara AM6526, AM6527, AM6528, AM6546, or AM6548 with dual-core or quad-core Cortex-A53 processor @ 1.1 GHz, dual Cortex-R5 dual-lockstep processor @ 400 MHz, optional Imagination SGX544 GPU (AM6xx8 SKU) System Memory – Up to 4GB DDR4 SDRAM with optional ECC Storage – Up to 64GB eMMC […]

2-Way Ethernet Splitters Sell for as low as One Dollar

When I need to connect more than one device over Ethernet I usually think Ethernet hub or Ethernet switch. I think the former is harder to find these days but was convenient to capture Ethernet packets with Wireshark. I had however never heard about Ethernet splitters until I saw a pair sold on Gearbest for $7.99, but soon found one on Aliexpress for just one dollar plus shipping. At first sight, it does not seem particularly useful especially when looking at the connection diagrams that show it used as some kind of Ethernet extender where you need to connect two Ethernet cables to the router, and again two cables to the targets since the same signal could be transmitted over a single cable with a $10 Ethernet switch at the other side. There’s a method to this (apparent) madness, as Cat 5E or grater cables come with 4 twisted pairs […]
