DORHEA 10PCS ESP-WROOM-32D ESP32 Bluetooth and WiFi Low Power Module integrates ESP32-D0WD Generic Wi-Fi+BT+BLE MCU Modules for Voice Encoding Music Streaming and MP3 Decoding
- ESP32-WROOM-32D, Core: ESP32-D0WD ; SPI flash: 32 Mbits, 3.3 V; Crysta: 40 MHz; Antenna: onboard antenna.
- ESP32-WROOM-32D are powerful, generic Wi-Fi+BT+BLE MCU modules that target a wide variety of applications, ranging from low-power sensor networks to the most demanding tasks, such as voice encoding, music streaming and MP3 decoding.
- The sleep current of the ESP32 chip is less than 5 A, making it suitable for battery powered and wearable electronics applications.
- ESP32-WROOM-32D integrate a 4 MB of external SPI flash. The integrated SPI flash is connected to GPIO6, GPIO7, GPIO8, GPIO9, GPIO10 and GPIO11. These six pins cannot be used as regular GPIOs.
- Flash integrated on the module and are not recommended for other uses.

Average: 80 mAMinimum current delivered by power supply: 500
mARecommended operating temperature range: 40 C ~ +85 CWhen external flash is mapped into CPU instruction memory space, up to 11 MB + 248 KB can be mapped at a time. Note that if more than 3 MB + 248 KB are mapped, cache performance will be reduced due to speculative reads by the CPU. When external flash is mapped into read-only data memory space, up to 4 MB can be mapped at a time. 8-bit, 16-bit and 32-bit reads are supported. External SRAM can be mapped into CPU data memory space. Up to 4 MB can be mapped at a time. 8-bit, 16-bit and 32-bit reads and writes are supported.
