Walter is present on the Embedded World 2023 fair in Nuremberg, Germany, from 14 - 16 March. You can find us in hall 3 booth 3-539. Enter your name and email to receive a free ticket within 48h. See you at the fair!
Although Walter has a powerful processor and many wireless technologies aboard, the module has a very small form factor of only 55mm x 24.8mm.
The ESP32-S3 microcontroller allows any peripheral to be routed to any IO pin. On top of that no exposed IO pins are strapping pins, this means you have the freedom to layout your Walter based board as you wish.
The board uses an ultra high efficiency DC-DC converter for optimal power performance.
Besides the various low power and deep sleep modes of both the ESP32-S3 processor and GM02SP modem, Walter has a mosFET switched and software controllable peripheral power pin. This allows you to completely remove power to attached devices, such as sensors, when you don't need them.
As certification and production is pending the prices are still subject to change. Please contact use for volume pricing.
