Vallarta MKR
Arduino MKR form-factor evaluation board for the Vallarta LPWAN module. Features the STM32WL MCU with ARM Cortex-M4 at 48 MHz and Semtech SX126x RF transceiver for sub-GHz long-range IoT prototyping.
Overview
The Vallarta MKR is an evaluation and prototyping board for the Vallarta LPWAN module in Arduino MKR form factor. It provides easy access to all module pins and wireless capabilities through standard headers.
Built around the STM32WL MCU with an ARM Cortex-M4 running at 48 MHz and an integrated sub-GHz radio, the board enables rapid development and testing of long-range IoT applications.
