STMod+ connector expansion board for STM32 Nucleo
The TIDA-00913 reference design implements a 48V/10A three-phase GaN inverter with precision shunt-based in-line phase current sensing for precise control of precision drives such as servo drives. One of the biggest challenges with shunt-based in-line phase current sensing is the high common-mode voltage transients during PWM switching. The INA240 bidirectional current sense amplifier uses enhanced PWM rejection to overcome this problem. This reference design provides an output voltage from 0 to 3.3V, regulated to ±16.5A, with a mid voltage of 1.65V, enabling highly accurate phase current over temperature. TIDA-00913 provides a TI BoosterPack-compatible interface to connect to the C2000 MCU LaunchPad™ development kit for easy performance evaluation.
The overall idea of the project is to use the GD32E231 development board as the main control unit, use the OLED12864 display screen as the human-computer interaction module, and connect the device to the cloud through the ESP8266 WIFI module set, so that basic intelligent functions can be initially realized.

Battery-powered water meters face a challenge: continuously measuring water flow information while consuming as little power as possible. The EVM430-FR6989 used in this design uses a MSP430 FRAM-based microcontroller, which can provide 100uA/MHz active mode current and 450nA standby mode current, support real-time clock function, and integrate low-power analog and digital peripherals. Additionally, the MCU offers virtually unlimited write endurance, fast/low power writes and data flexibility. This reference design demonstrates how to use the integrated Extended Scan Interface (ESI) on a microcontroller to achieve ultra-low power consumption (versus the same detection method using external circuitry). In a water meter design, if coupled to the LC rotation detection sensor (supplied), the ESI continuously detects thruster rotation while the rest of the microcontroller is in a low power mode. The design automates the measurement process and reduces CPU involvement by using the ESI integrated in the MSP430 MCU, which helps reduce overall power consumption.
The indoor environment monitoring terminal can monitor the indoor environment (temperature, humidity, lighting and other parameters). The terminal is equipped with a liquid crystal display module; it can realize real-time display of environmental parameters and clocks. The terminal is equipped with an audible and visual alarm circuit, which can set a certain When the parameters exceed the limit value, an audible and visual alarm will be issued; the terminal is equipped with a Bluetooth function, and the mobile phone can communicate interactively with the terminal through Bluetooth. It can realize functions such as detection terminal system time upload, real-time parameter query, sound and light alarm switch control, scheduled upload switch control, and alarm threshold setting.
This reference design allows a digitally programmable power supply to power a continuous wave (CW) mode ultrasound transmitter circuit via a 24V bus. There are two adjustable outputs (±2.5 to ±12V) under user software control. These outputs provide positive and negative regulator outputs up to 2A with very low ripple and noise. By adding more regulators in parallel, the power supply can be scaled to provide higher output currents up to 3A. The power supply can also be synchronized to an external clock.
