WiFiG25 is a cost-effective System-on-Module (SoM) thought of to drastically reduce the development time needed to design a low-power and low-EMI Linux Embedded device.

The more complex hardware like CPU, RAM, Flash, Ethernet, power and EMI components are integrated on a single SMD component in just 40x40 mm (1.57x1.57 inch) using an complex six layers PCB permitting hardware designers to create their simple and cheap carrier boards.

What you have to know before buying CORE9G25 SoM

The CORE9G25 prices are fixed so don't change for hi-volume batch, the follow is the quantity price:

Item Description Temperature Range <1000Pcs Delivery After pay
WiFiG25-128 128MB DDR2 RAM+256MB Flash  0° +70° $29.9 Two Days
WiFiG25-128-I 128MB DDR2 RAM+256MB Flash -20° +85° $35 Four Weeks
WiFiG25-256 256MB DDR2 RAM+256MB Flash   0° +70° $39 Four Weeks
WiFiG25-256-I 256MB DDR2 RAM+256MB Flash -20° +85° $45 Four Weeks

These are the main reasons:

  • WiFiG25 is a Made in China product and you can buy directly it from the China factory so no resellers charges are applied to the final cost
  • Since it is made in-site we can apply the same discount for one or 1K boards because in every case we have to make the board one by one and we have access to hi-volume prices from our provider for components used on it
  • Each order is paid for in advance so you don't have to pay any interest rates
  • You can buy the WiFiG25 on-line using our website or by contacting directly us. We can speak English.

Warranty terms

We make deep functionality tests on any outcoming board and the warranty does not cover boards which have been left out of its original enclosure for a long time (max 10 days) or when the pads are welded (please read the terms and conditions for more details).

Incoming test equipment

If you need to do an incoming quality test before mount the boards, we can provide a copy of our functionality test equipment we using for our outcoming tests contact us for more info and pricing.

Custom boards based on WiFiG25

If you like WiFiG25 but have no time (or skill) to design and produce an OEM device by yourself, please Contact US(support@armdevs.com), we could help you to create your custom project.
