Interesting article. I looked around, the ESP32 from Espressif is primarily designed for:
• IoT devices
• Embedded systems
• DIY electronics projects
• Smart home appliances
• Wearables (basic fitness trackers or smartwatches, but not Apple, Samsung, Galaxy, Fitbit)
• Industrial automation
Major phones and tablets typically use advanced, high-performance wireless chipsets (from Qualcomm, MediaTek, Broadcom, or Apple) that support higher data throughput, power efficiency, and cellular connectivity—features beyond what the ESP32 offers.
ESP32 chips excel in low-power, cost-sensitive applications where integrated Wi-Fi/Bluetooth capability is required, but not in consumer smartphones or tablets, which demand more robust, power-efficient, and higher-performance hardware.
