Preview of W5500IoT in WIZ820io footprint + opt CPU

Question

I am just finalizing my W5500 design and have squeezed it into the same footprint as the WIZ820io which I have been using in another design. So this new module can drop in without changes into this older design and also multipurposes some of the pins to simplify interfacing in newer designs. There was also room to incorporate a small Cortex M0 + 16Mbit Serial Flash on-board as which means when I port my very compact code over then it can not only run as a serial server but also web and ftp as well, so it’s stand-alone too!. I’ve brought out Rxd and Txd onto the 10 pins in compatible format as well. The idea is that the M0 would always allow access to the host system even if the host software is in control normally. The reset is also bidirectional so it can reset or hold the host in reset if necessary, perfect for remote debugging or serial ISP. Since WIZnet only had chunky W5500 modules I was forced to do it my way and make a few improvements along the way too Although this is primarily for internal use I may consider selling them as well.

[quote=“midnightcow”]Hi, Peterjak. Can you show me the photo of W5500Iot module ? Thank you.[/quote] This has been renamed IoT5500 so as not to be confused with WIZnet modules. [url]Dropbox - Error

Latest product shot of both the IoT5500 module plus the optional +P8 network/file server with microSD header (or 16MB SPI Flash). The +P8 is normally sandwiched on top of the IoT5500 pcb to form a complete stand-alone HTTP/FTP server plus telnet and SMTP. So the W5500 can either be interfaced normally via SPI to the host CPU or the host CPU can interface serially to the +P8 network/file server to offload this overhead. The +P8 can even perform datalogging at the same time. 910×397 80.3 KB Interactive session [size=85][code]Tachyon> ifconfig ************ NETWORK STATUS ************ HARDWARE: CE1432 P8M using WIZnet W5500 LINK UP CHIP VER 0004 SRC IP 192.168.016.150.

Hi, peterjak. I like your logo on the PCB. In my case, I like to write the name of the girl group idol on the PCB.
