Synchronous rectifier design for isolated high power PoE+ (802.3 at and bt) applications can help increase efficiency and reduce heat.
MCUs like STM32 and i.MX RT1050 series have a 24-bit parallel RGB interface for displays. RGB to MIPI DSI converters allow DSI displays.
ESP32 supports Wi-Fi, ethernet, PPPoS modem and other custom networking interfaces. Using esp_netif, you can search network interfaces.
I list some cases with using SIM commands like AT+CIMI which result in “ERROR: SIM failure”. Common problems are listed along with solutions.
Here is how you can power multiple servo motors from a LiPo battery pack. This is the best option to power hexapods and humanoid robots.
Notes on using STM32 with ESP32 AT Module. The PCB Artists ESP32 AT SDIO module is loaded with SDIO AT firmware for use with IoT designs.
ESP32 4G modem interface allows you to add cellular internet connectivity to your IoT designs. Find schematics, PCB guidelines and code here.
STM32 RGB display output can be used to drive LVDS LCD displays. In this article, we cover the basics of STM32 LVDS interface with example.
Adding WiFi to STM32 can open up a lot of possibilities for IoT and industrial automation applications. We explore some STM32 WiFi options.
Here are some steps on how to port U-Boot bootloader to a new, custom i.MX6 Linux board. Follow along to create a defconfig for your board.
