AltIMU-10 v5 Gyro, Accelerometer, Compass, and Altimeter
The Pololu AltIMU-10 v5 is an inertial measurement unit (IMU) and altimeter that features the same LSM6DS33 gyro and accelerometer and LIS3MDL magnetometer as the MinIMU-9 v5, and adds an LPS25H digital barometer. An I²C interface accesses ten independent pressure, rotation, acceleration, and magnetic measurements that can be used to calculate the sensor’s altitude and absolute orientation. The Pololu AltIMU-10 v5 is a compact board that combines ST’s LSM6DS33 3-axis gyroscope and 3-axis accelerometer, LIS3MDL 3-axis magnetometer, and LPS25H digital barometer to form an inertial measurement unit (IMU) and altimeter.

SparkFun Air Quality Breakout – CCS811
The CCS811 Air Quality Breakout is a digital gas sensor solution that senses a wide range of Total Volatile Organic Compounds (TVOCs), including equivalent carbon dioxide (eCO2) and metal oxide (MOX) levels. VOCs are often categorized as pollutants and or sensory irritants and can come from a variety of sources like construction materials, machines and even people. This breakout is intended for indoor air quality monitoring in personal devices such as watches and phone.

SparkFun Atmospheric Sensor Breakout – BME280
The SparkFun BME280 Atmospheric Sensor Breakout is the easy way to measure barometric pressure, humidity, and temperature readings all without taking up too much space. Basically, anything you need to know about atmospheric conditions you can find out from this tiny breakout. The BME280 Breakout has been design to be used in indoor/outdoor navigation, weather forecasting, home automation, and even personal health and wellness monitoring.

SparkFun Thing Plus – ESP32 WROOM
The SparkFun ESP32 Thing Plus is the next step to get started with Espressif IoT ideations while still enjoying all the amenities of the original ESP32 Thing. Espressif’s ESP32 WROOM is a powerful WiFi and Bluetooth MCU module that targets a wide variety of applications. At the core of this module is the ESP32-D0WDQ6 chip which is designed to be both scalable and adaptive. To make the Thing Plus even easier to use, we’ve moved a few pins around to make the board Feather compatible and it utilizes our handy Qwiic Connect System which means no soldering or shields are required to connect it to the rest of your system.
The ESP32 Thing plus integrates a rich set of peripherals, ranging from capacitive touch sensors, SD card interface, Ethernet, high-speed SPI, UART, I2S and I2C. Thanks to the onboard ESP32 WROOM module, the SparkFun Thing Plus features 16MB of flash memory, 520kB of internal SRAM, an integrated 802.11 BGN WiFi transceiver and dual-mode Bluetooth capabilities, and a JST connector to plug in a LiPo battery.

ACTION Commands
Begin by sending the inquiry scan command: I,
If the modem finds any modules, you can try sending the connect command: C,
< to connect to one of them. The modem in the example above found one devices in range, by sending the C,0006664FAE18 command, we can attempt to connect to one of them. After sending the connect command, the device will respond with "TRYING", which will be followed by either "CONNECT failed" or the connection will be successful. After a successful connection we immediately enter data mode, and the modem becomes a pipeline. Any characters sent from one Bluetooth device will be sent to the other, and vice-versa.

Moteino
Moteino began as a low power wireless Arduino compatible development platform based on the popular ATmega328p chip used in the Arduino UNO. Moteinos are compatible and can communicate with any other Arduino or development platform that uses the popular HopeRF RFM69 or LoRa transceivers, or even the older RFM12B. Moteino also comes with an optional SPI flash memory chip for wireless programming, or data logging. Moteino was designed to be a compact, highly customizable and affordable development platform, suitable for IoT, home automation and long range wireless projects.
Moteino in RFM12B to rebuild suggests doing as new without completely replacing. I decided to stripped down at RFM12B and rebuild in Bluetooth.

MPU-9150
MotionInterface is becoming a “Must-Have” function being adopted by smartphone and tablet manufacturers due to the enormous value it adds to the end user experience. In smartphones, it finds use in applications such as gesture commands for applications and phone control, enhanced gaming, augmented reality, panoramic photo capture and viewing, and pedestrian and vehicle navigation. With its ability to precisely and accurately track user motions, MotionTracking technology can convert handsets and tablets into powerful 3D intelligent devices that can be used in applications ranging from health and fitness monitoring to location-based services. Key requirements for MotionInterface enabled devices are small package size, low power consumption, high accuracy and repeatability, high shock tolerance, and application specific performance programmability, all at a low consumer price point.

SparkFun 9 Degrees of Freedom – Sensor Stick
The SparkFun 9DOF Sensor Stick is a very small sensor board with 9 degrees of freedom. It includes the ADXL345 accelerometer, the HMC5883L magnetometer, and the ITG-3200 MEMS gyro. The “Stick” has a simple I2C interface and a mounting hole for attaching it to your project. Also, the board is a mere allowing it to be easily mounted in just about any application.

Micro OLED
Micro OLED displays are silicon-based OLED display that use a monocrystalline silicon wafer as the actively driven backplane, so it is easier to achieve high PPI (Pixel Density), a high degree of integration, and small size. This ensures they are easy to carry, have good anti-seismic performance, and have ultra-low power consumption.

Multi-Motor Control
In order to synchronize the multi-motor system, a novel method for this system based on embedded control terminal. A controller of the strategy with the function of synchronous control is also completed. According to the requirements of this system, a distributed control structure which based on Hierarchical Approach is chosen. The hardware platform of this structure is composed of embedded control terminal motor could be driven independently. The experiment results verified that the multi-motor system is reliable, the control strategy is rational applied this multi-motor system has better dynamic response and higher reliability.
