It's clear that almost any business and developer will benefit from IoT. Walter allows you to build your next connected thing in a breeze. Given that the module will be CE and FCC certified your product certification costs will be reduced to a minimum.
The Walter module schematics will be released under the GPLv3 license.
The Walter module will be CE and FCC certified to shorten your time to market.
All I/O pins are available without limitations which gives you ultimate layout flexibility.
Program the module with the Arduino IDE, Micropython, JavaScript or the Espressif IDF.
Walter's ESP32-S3 offers WiFi and BLE, the Sequans modem has NB-IoT, LTE-M and GPS.
The module is designed and produced in the European Union to offer long term availability.
We promise we won't spam you with daily mail. You will be kept up-to-date about our upcoming crowdfunding campaign, hardware and software updates.
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.
