The A3053 Embedded Ethernet Module, designed by Open Source Instruments, is in pre-launch at Crowd Supply. The A3053 allows you to control your electronic circuit over TCP/IP using a wired Ethernet connection. Its programmable host interface can implement a 50-ns, 16-bit parallel bus, or half a dozen 20-Mbps serial interfaces, as well as analog inputs and pulse-width-modulated outputs. The A3053 is powered by a PIC32MZ2048EFH microcontroller and built on an industry-standard mPCIe card. The A3053 hardware and software are open-source. We designed the A3053 to take the place of the discontinued RCM6700 ethernet module designed by Rabbit Semiconductor years ago. If you have been using the RCM6700, we invite you to consider the A3053 as a way to avoid re-designing your host board. We are already making these for use in our own instruments, but we will make 500 of them if our Crowd Supply campaign is successful. Crowd supply pre-launch page is
