ESP32U WIFI Module for SKR 3/ SKR 3 EZ/ SKR 2 / Octopus / Octopus pro

The ESP32-WROOM-32UE is a powerful and versatile general-purpose Wi-Fi+BT+BLE MCU module. It can be used in low-power sensor networks and demanding tasks such as speech encoding, audio streaming, and MP3 decoding. ESP32-WROOM-32UE adopts IPEX antenna and is configured with 4MB SPI flash Key Features: MCU • Built-in ESP32-D0WD-V3 chip, Xtensa® dual-core 32Bit LX6 microprocessor supporting clock frequencies up to 240 MHzRate • 448 KB ROM • 520 KB SRAM • 16 KB RTC SRAM WI-FI • 802.11b/g/n • 802.11n data rates up to 150 Mbps • Supports A-MPDU and A-MSDU aggregation • Supports 0.4 µs guard interval • Working channel center frequency range: 2412 ~ 2484 MHz Bluetooth® • Bluetooth V4.2 BR/EDR and Bluetooth LE standards • Class-1, class-2 and class-3 transmitters • AFH • CVSD and SBC Hardware • Module interface: SD card, UART, SPI, SDIO, I2C, LED PWM, Motor PWM, I2S, IR, Pulse Counter, GPIO, capacitive touch sensor, ADC, DAC, etc. • Operating voltage/supply voltage: 3.0 ~ 3.6 V • Recommended operating temperature range: –40 ~ 85 °C ESP32 has 5 strapping pins • MTDI • GPIO0 • GPIO2 • MTDO • GPIO5 The ESP32-D0WDQ6 contains two low-power Xtensa® 32-bit LX6 MCUs. On-chip storage includes: • 448 KB of ROM for program startup and kernel function calls • 520 KB on-chip SRAM for data and instruction storage • RTC fast memory, which is 8 KB of SRAM, can be used for data storage and by the main CPU when the RTC starts up in Deep-sleep mode access. • RTC slow memory, which is 8 KB of SRAM, can be accessed by the coprocessor in Deep-sleep mode. • 1 Kbit of eFuse, of which 256 bits are dedicated to the system (MAC address and chip settings); the remaining 768 bits are reserved for user programs, which include flash encryption and chip ID.

Compatible with BTT SKR 3, SKR 3 EZ, SKR 2, Octopus, and Octopus Pro Boards.
