1. Overview ! 1. Overview RIGEL REV C is an ESP32-based customized module developed by Espressif for Whirlpool. • W11261889, which features two PCB antennas plus one IPEX/U.FL antenna. RIGEL REV C features an 16 MB external flash. The ordering information of RIGEL REV C is listed in Table 1-1. Table 1-1. Ordering Information of RIGEL REV C Part number Embedded chip Flash Antenna W11261889 ESP32-D0WD 16 MB 2 × PCB antennas, 1 × IPEX/U.FL antenna At the core of the module is ESP32-D0WD chip, one of the SoCs among the ESP32 series. The chip contains two low-power Xtensa® 32-bit LX6 microprocessors that can be individually controlled, and the CPU clock frequency is adjustable from 80 MHz to 240 MHz. The user may also power off the CPU and make use of the low-power co-processor to constantly monitor the peripherals for changes or crossing of thresholds. The chip integrates a rich set of peripherals, ranging from capacitive touch sensors, Hall sensors, SD card interface, Ethernet, high-speed SPI, UART, I2S and I2C. ESP32-D0WD's internal memory includes: • 448 KB of ROM for booting and core functions. • 520 KB of on-chip SRAM for data and instructions. • 8 KB of SRAM in RTC, which is called RTC FAST Memory and can be used for data storage; it is accessed by the main CPU during RTC Boot from the Deep-sleep mode. • 8 KB of SRAM in RTC, which is called RTC SLOW Memory and can be accessed by the co-processor during the Deep-sleep mode. • 1 Kbit of eFuse: 256 bits are used for the system (MAC address and chip configuration) and the remaining 768 bits are reserved for customer applications, including flash-encryption and Chip-ID. 📖 Note: For more information on ESP32, please refer to ESP32 Datasheet.
