Teyleten Robot D1 Mini ESP32 ESP-WROOM-32 WLAN WiFi+Bluetooth Internet of Things IoT Development Board for Arduino NodeMCU (3pcs)

Brand: Teyleten Robot

Features:

• Mini ESP32 contains two low-power 32-bit LX6 MCUs.
• 448 KB of ROM, used for program startup and kernel function calls
• 520 KB on-chip SRAM for data and instruction storage
• The 8 KB of SRAM in RTC, that is, RTC slow memory, can be accessed by the coprocessor in Deep-sleep mode
• The 8 KB of SRAM in the RTC, that is, the RTC fast memory, can be used for data storage and accessed by the main CPU when the RTC is started in Deep-sleep mode
• 1 kbit eFuse, of which 256 bits are dedicated to the system (MAC address and chip settings); the remaining 768 bits are reserved for user applications, which include Flash encryption and chip ID
• Mini ESP-32 integrates 4MB of SPIFlash
