Description
Reviews

The Walter is a compact development board based on an ESP32-S3 microcontroller with numerous connectivity options that can be easily programmed, for example via the Arduino IDE. In addition, the board has a very low power consumption and is fully CE/FCC certified. The certification has been carried out with the following antennas (although other antennas can of course also be used):

LTE: Taoglas FXUB63
GNSS: Taoglas FXP611

Note: No antennas for GNSS and LTE are included.

Note: When using/activating LTE, an antenna must be connected, otherwise the module may be permanently damaged.
