MCU: ESP32-D0WDQ6:
Dual-core processor with up to 600 MIPS of computing power and adjustable clock frequencies ranging from 80 MHz to 240 MHz. The chip integrates 448KB ROM, 520KB SRAM, and 16KB RTC SRAM. WIFI supports the 2.4G 802.11b /g/n wireless standard with 802.11n (2.4GHz) speeds up to 150 Mbps. Supports the full BTv4.2 standard, including traditional BT(BR/EDR) and low power BT(BLE).
PSRAM: ESP-PSRAM64H:
The ESP-PSRAM64H is a 64 Mbit(8-byte) pseudo-static random access memory (Pseudo SRAM) manufactured using a high-performance and highly reliable CMOS process with an operating voltage of 3.3V and a transmission speed of 40 MHz connected to the MCU via a serial peripheral interface (SPI).
Flash: GD25Q127CSIG:
The 128Mbit(16M byte) capacity serial flash memory is connected to the MCU via the Serial Peripheral Interface (SPI) with a transfer speed of 40 MHz by default.
USB-UART: CP2104:
CP2104 is a highly integrated USB to UART bridge controller, which is responsible for the communication protocol conversion from the host to the host computer, so as to facilitate the program burning and serial debugging of the host. The development board is equipped with an automatic download circuit, which can be downloaded with one click without pressing any key.
Power Manager: IP5306(I²C):
The IP5306 is a versatile power management SOC that integrates a boost converter, lithium battery charge management, and battery level indication. The external battery can be managed with the base, and the battery charging status and remaining power can be read through I2C protocol communication. In battery mode, click the reset button to power on the host and double-click to shut down the host.
Speaker:
8Ω0.5W speaker, output by DAC(digital-to-analog converter) connected to the ESP32 after amplification.
LCD: ILI9342C:
2.0 “(320*240)TFT LCD, the driver IC is ILI9342C through the serial peripheral interface (SPI) to communicate with the ESP32, the maximum speed can reach 60MHz.
Touch screen: FT6336U:
The FT6336U is a single-chip capacitive touch screen controller IC with self-capacitive technology that supports single and gesture touch or two points. To communicate with the ESP32 through the I²C bus, the coordinates of the three virtual keys at the bottom of the screen are (60,400), (180,400), and (300,400). The FT6336U is mounted on the internal I²C bus of the host and supports a maximum communication rate of 400k.
Micro SD Card(TF card):
Support self-ejecting self-locking TF card slot, maximum support 16GB standard TF card.
Gyroscop: MPU-6886:
The MPU-6886 is a six-axis motion sensing device that integrates a three-axis gyroscope and a three-axis accelerometer, including an on-chip 16-bit ADC, programmable digital filter, embedded temperature sensor, and programmable interrupts. It is mounted on the internal I²C bus of the host and supports up to 400k communication rate.
Magnetome: BMM150
The BMM150 is an independent geomagnetic sensor that allows the measurement of magnetic fields in three vertical axes. It is mounted on the internal I²C bus of the host and supports up to 400k communication rate.
Antenna:3D antenna
Battery:
Removable 150mA 3.7v lithium-ion battery is used as the base plate to connect to the main engine through a pin row.
RGB LED：SK6812
RGB LED lights mounted on a standard battery base are connected to the host via a single bus.
Extern Power:
USB Type-C provides 5V input for external power supply.
PH2.0 Port:
The PY2.0 motherboard is used to connect other Rubik modules to expand functionality.
Pin Port:
Lead out a group of 2.54 1*15+1*8 pin bars on the base for expanding external devices.
