However, being a product still in preview, programming is limited to the ESP-IDF framework, which could present a barrier for some developers. Despite this, its capabilities, especially in relation to Wi-Fi 6 and advanced Bluetooth, could justify the investment, particularly for IoT and HMI projects. It’s crucial to keep an eye on compatibility updates and future software versions to maximize the value of this product.
