T-Display-S3-AMOLED-1.43 – A 1.43-inch round AMOLED touchscreen display with an ESP32-S3 wireless MCU

T-Display-S3-AMOLED-1.43

We’ve already seen a few ESP32-S3 boards with an AMOLED display and plenty with round displays such as SB Components’ Dual Roundy, LILYGO T-RGB ESP32-S3, MaTouch ESP32-S3 Rotary IPS display among others, but I had yet to see an ESP32-S3 board with a round AMOLED display. That’s just what the LILYGO T-Display-S3-AMOLED-1.43 has to offer. The ESP32-S3 board features a 1.43-inch round AMOLED with 466×466 resolution and a capacitive touchscreen, a microSD card slot for storage, an RTC with backup battery, two 14-pin headers and a Qwiic UART connector for expansion, a USB-C port for power/charging and programming, and a 2-pin connector for a LiPo battery.

Infineon AIROC CYW20829 Bluetooth LE 5.4 MCU and module family targets industrial, consumer, and automotive applications

Infineon AIROC CYW20829 Bluetooth Low Energy 5.4 microcontrollers

Infineon has recently released the AIROC CYW20829 Bluetooth LE (Low Energy) 5.4 family which now includes SoCs and modules. These SoCs include two Cortex-M33 MCU cores: one 48 or 96 MHz application core for the peripherals, security, and system resources, and one communication core for the 2.4 GHz RF transceiver with up to 10 dBm transmit power and -98 dBm receive sensitivity. This high integration reduces bill-of-material (BOM) costs for a wide variety of applications, including PC accessories, low-energy audio, wearables, solar micro inverters, asset trackers, home automation, and others. Back in 2021, we saw Infineon release the AIROC CYW5557x family of Wi-Fi 6/6E SoCs for IoT and streaming devices with features like enhanced range and improved network efficiency. More recently,  Infineon announced the PSOC Edge E81, E83, and E84 MCU based on Cortex-M55/M33 microcontrollers. Feel free to check those out if you are looking for Infineon-specific MCUs.
