This is an archive article published 08/26/2014. Some information may no longer be up to date and in line with the current state. Please contact us in case of interest.

Basic version of the WiFi module WizFi250 from company WizNet is probably familiar to you from our article WizFi250 - WiFi quickly, easily and cost-effectively. The newest modification of this module is a version with a „H“ suffix marking a version with a pin-header.

As you already may suspect, it is a version intended for development, as the module doesn´t have to be soldered to a baseboard (by means of hot-air reflow). WizFi250-H can be beneficial not only for development, but also for usage in a target device, where it isn´t necessary to maintain the lowest possible construction height (baseboard + WiFi module). At the same time, this combination enables to assemble another components on a baseboard - below the WiFi module.

WizFi250H - when a small difference can help significantly
From the construction point of view, the WizFi250-H module is solved as a combination of the WizFi250 module with a small PCB with 2x double pin header (1.25mm). As for other features, the module is identical to the original module, that´s why they have the same datasheet WizFi250. WizFi250H can be used with the WizFi250-EVB development board. We bring you a comparison of both versions - with and without a pin header on attached pictures.
