SensorTag TI Design

The new SimpleLink™ multi-standard SensorTag kit helps you realize your Internet of Things (IoT) product ideas. The kit contains 10 low-power MEMS sensors in tiny packages that are expandable using DevPacks, making it easy to add your sensors or actuators. Connect to the cloud via Bluetooth® and get sensor data online in three minutes. SensorTag works right out of the box with iOS and Android apps, so no programming experience is required to get started. The new SensorTag is based on the CC2650 wireless microcontroller (MCU) and consumes 75% less power than previous Bluetooth products. Therefore, the SensorTag kit can be battery powered and a coin cell battery will last for many years. Bluetooth SensorTag contains iBeacon technology. As a result, your phone can launch apps and customize content based on SensorTag data and physical location. Additionally, SensorTag kits are enabled via ZigBee® and 6LoWPAN technologies.

Open source AutoQuad flight control based on i.MXRT1052

This is an original work by netizen jiezhi320 who participated in the RT-Thread application competition. In 2015, jiezhi320 made a version of hardware based on stm32f405rgt6. However, due to the high CPU usage of the UKF algorithm, the author migrated it to imx-rt1052, in order to leave enough resources for everyone to develop in-depth for model friends.

This reference design is for a buck-boost LED driver. The MAX16834 current-mode high-brightness LED driver is featured, and the MAX16834 EV (evaluation) kit is used to implement the design. The application note shows the design specifications, schematic, bill of materials (BOM), and performance data.

Design of automatic goldfish feeding robot based on GD32E231

If you are away from home for a long time on a business trip, the goldfish at home will starve. Therefore, in order to prevent goldfish from starving when the owner is not at home, an automatic feeding robot was designed based on a 4-degree-of-freedom robotic arm and GD32E231. GD32E231 controls the robotic arm by generating PWM. At the same time, it picks up fish food from a fixed place and puts it into the fish tank according to the preset time. Through multiple manual trainings, the robotic arm automatically calculates the feeding based on the manual training data. eating position. At the same time, you can also add some auxiliary functions. You can roughly obtain the internal temperature of GD32E231 and the lighting conditions around the fish tank through the serial port or onboard ADC and photoresistor. You can turn on lighting equipment such as desk lamps when it is dark.

15-Cell Li-Ion Battery Controller Analog Front-End Reference Design

The TIDA00255 reference design utilizes the bq76940 analog front end (AFE) IC. It can measure battery voltage, mold temperature or external thermistor voltage using a 14-bit ADC. Current is measured individually by a separate 16-bit coulomb counter. The design turns off the low-side power FET to stop discharging or charging based on selected hardware limits. A microcontroller not included in this design will be part of the battery controller to communicate with the AFE to set protection thresholds, enable the power FETs, provide fault recovery, and shut down the FETs during over/under temperature conditions. Battery controller designs may include additional features that are not part of this reference design, such as secondary overvoltage protection, measurement, and isolated communications to inform the system of battery status.
