This repository contains all information and documentation about Walter and additional motherboards for Walter. Walter is a board designed by DPTechnics which combines an ESP32-S3 and a Sequans Monarch 2 in a small form factor IoT module. This gives Walter a vast amount of wireless connectivity options such as:
- Bluetooth Low Energy 5.0
- 1T1R WiFi b/g/n
- LTE Cat-M1 (LTE-M)
- LTE Cat-NB1 (NB-IoT rel. 13)
- LTE Cat-NB2 (NB-IoT rel. 14), ready for rel. 15
- GNSS receiver (GPS and Galileo)
Besides these you get all the goodies from the ESP32-S3 chip such as SPI, I2S, I2C, PWM, RMT, ADC, UART, SD/MMC host and TWAI.
We design and manufacture Walter in Belgium and guarantee that the board will be available for a minimum of 10 years. This makes Walter a solid choice to design your next LPWAN IoT product with.
All documentation for Walter is open source and we welcome all contributions are more than welcome.
All documentation is created in markdown and it is visualized by docsify on the quickspot website. The documentation website can be found here: https://www.quickspot.io/documentation.html
