Electrical Characteristics 1. 1. Overview 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 ash. 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 W11261889 ESP32-D0WD Flash 16 MB Antenna 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 conguration) and the remaining 768 bits are reserved for customer applications, including ash-encryption and Chip-ID. Note:
For more information on ESP32, please refer to ESP32 Datasheet. The two PCB (slot) antennas supported on RIGEL REV C have the following specications listed in Table 1-2:

3. Peripherals and Interfaces 3. Peripherals and Interfaces 3.1. Radio/SOC & Class B Micro UART should be used to interface between the Radio/SOC and the class B micro. The Radio/SOC provides a wake-up input line (GPI39_WKUP_IN) and an interrupt output line
(GPIO15_WKUP_OUT_MTDO) to the class B micro. 3.2. Radio/SOC & WIN Bus The Radio/SOC provides UART communication (GPIO27_WIN_TX/GPI37_WIN_RX) to the WIN bus for optional use. Flow control is not required. 3.3. InterfaceDisplay The Radio/SOC provides eight signal lines (a 4-line SPI and 4 GPIOs) to display:
Display reset SPI data out from display SPI SS SPI CLK SPI data in to display Display CD Display TE Display control for back-light driver 3.4. InterfaceJATG The Radio/SOC provides a JTAG interface for debugging. However, this interface should only be used during the development. 3.5. InterfaceProgramming The Radio/SOC provides a standalone programming interface, which includes UART0_RX, UART0_TX, GPIO0_I2S_CLK/Boot, EN, VDD and GND. Espressif Systems
