4.1 SDK for Open CPU modules
As NORA-W10 Open CPU modules are delivered without flashed software, you develop your
application design using the utilities and device-level APIs supported by the module chipset supplier.
The ESP-IDF Software Development Kit
[6] is available from the Espressif website. It bundles the
Wi-Fi stack and the broad range of drivers and libraries necessary for building your development
environment.
Figure 10 shows the architecture of NORA-W10 Open CPU software in relation to the MCU,
transceiver and ESP-IDF SDK.
