>>>Manual: Click here to open<<<Rubik Bit-1 Character:
Rubik Bit 1 is the smallest development board host in the Rubik family, with a size of only 20*20*20(mm). It is a standard cube design structure. Two PCBs are stacked, and 8 RGB LEDs are installed on the 8 sides of the host to illuminate the host in all directions.The host adopts ESP32(ESPressif) system-level encapsulated chip (SIP) ESP32-PICO-V3-02, integrated with 2.4GHz Wi-Fi and Bluetooth, and internally integrated with 8MBFLASH and 2MBPSRAM.External lead 2* 6PIN bus, used to expand external equipment to give play to the powerful performance of ESP32.
Functions overview:
MCU: ESP32-PICO-V3-02ESP32-PICO-V3-02 is a system-level encapsulated chip (SIP) with a dual-core ESP32 and a clock frequency range from 80 MHz to 240 MHz. It is a single-chip solution that integrates 2.4GHz Wi-Fi and Bluetooth dual-mode, using a TSMC ultra-low-power 40 nm process.ESP32-PICO-V3-02 SIP has crystal oscillator, 8M(byte) FLASH-2M (byte)PSRAM, filter capacitor, RF matching link and other peripheral devices seamlessly integrated into the package.
USB-UART: CH552TCH552T is a highly integrated USB to UART bridge controller, which is responsible for the communication protocol conversion between the host computer and the host computer to facilitate the program burning and serial port debugging of the host computer.The development board is equipped with automatic download circuit, which can be downloaded with one key without pressing any key.
Gyroscop: MPU-9250The MPU-9250 is a six-axis motion sensing device with an integrated three-axis gyroscope, three-axis accelerometer, three-axis magnetometer, and Digital Motion Processors (DMP).It is mounted on the internal I²C bus of the host and supports up to 400K communication rate.
RGB LED: SK6812The host board carries 8 sk6812 lamp, which is controlled by a single bus and the whole light is exposed in a series of only one IO.
BuzzerIt carries a passive buzzer
Pin PortThe back of the host machine leads to 2*6 rows of 2.0 spacing, which is used to expand external equipment.
