SB’s Dual Roundy and Squary Displays are powered by RP2040 or ESP32-S3 microcontrollers (Crowdfunding)

Dual Display Modules Roundy and Squary by SB Components

SB-Components has launched Dual Roundy and Dual Squary display modules powered by Raspberry Pi RP2040 or ESP32-S3 microcontrollers. These compact modules feature a 6-DoF IMU, interchangeable displays, and multiple storage and connectivity options. The Dual Roundy is equipped with two 1.28-inch round displays, with a 240 x 240 resolution, and uses the GC9A01 display driver IC. In contrast, the Dual Squary features two 1.54-inch square displays with a 240 x 240 resolution but utilizes the ST7789 display driver. Both displays offer a choice between a Raspberry Pi RP2040 MCU and the ESP32-S3-WROOM-1 module catering to different needs in performance and wireless capabilities. We’ve previously explored other rounded displays like the MaTouch ESP32-S3, T-RGB ESP32-S3, and ESP32-S3 Round SPI TFT. We’ve also examined other products from SB Components such as the Cluster HAT, PiMecha, PiTalk 3G HAT, and Micro RP2040. Feel free to check these out for more interesting tech insights. […]

Espressif announces the ESP32-C61 WiFi 6 SoC with improved affordability and wireless connectivity

Espressif has announced the ESP32-C61 SoC, a new ESP32-Cx chip with improved wireless connectivity, and expanded memory options. The ESP32-C61 builds upon the foundation laid by previous ESP32-Cx chips, such as the ESP32-C2 and ESP-C3, and its specifications appear to be quite similar to the ESP32-C6 launched in early 2023, but this SoC also adds support for the BLE Mesh 1.1 protocol and Quad SPI PSRAM at a frequency of up to 120MHz. It supports WiFi 6 on two modes (802.11ax and 802.11b/g/n) and includes a Bluetooth 5 (LE) radio with support for long-range operation through advertisement extension and coded PHY. The TWT (Target Wake Time) feature is supported in 802.11ax mode to save power, as well as OFDMA (Uplink/Downlink) and MU-MIMO (Downlink) for a high-quality, low-latency connection between devices. ESP32-C61 specifications: CPU – Single-core, 32-bit RISC-V microcontroller that can be clocked up to 160MHz Memory: 320KB on-chip SRAM 256KB […]

The EQSP32 is a no-code, no-solder Industrial Internet of Things Controller powered by a generative AI assistant (Crowdfunding)

The EQSP32 controller is a complete, end-to-end solution for IoT applications that recently launched on Kickstarter. It is a compact, wireless Industrial IoT controller based on the ESP32-S3 wireless SoC with a 250MHz dual-core processor, 512KB of RAM, and 8MB of flash memory. The product leverages artificial intelligence and code for automation projects can be generated automatically by the bundled generative AI programming assistant. The EQSP32 controller features 16 terminals that can be configured as analog or digital inputs, or as digital outputs. Switches, pushbuttons, keypads, LED strips, sensors, servos, potentiometers, etc., can be connected to these terminals. It is similar to the EdgeBox-Edge-100 we covered a while back but lacks an Ethernet port and uses less power overall. EQSP32 specifications: SoC: Espressif Systems ESP32-S3 dual-core Tensilica LX7 microcontroller @ 240 MHz, 512KB RAM Memory – 8MB flash Network Connectivity: Bluetooth, WiFi USB – USB-C programming port I/O: 16 multipurpose […]

Review of Elecrow’s 3.5-inch and 7.0-inch ESP32 display modules using Arduino programming

Using the ESP32 7.0-inch display as a dashboard

Hello, I’m excited to review the ESP32 display modules and HMI touchscreens from Elecrow with sizes ranging from 2.4 to 7.0 inches. For this review, Elecrow kindly provided me with both 3.5-inch and 7.0-inch models. While their screens differ in size, both modules share several components, such as the ESP32 microcontroller, making them adaptable options for a variety of projects. The Elecrow 7.0-inch display module is powered by the ESP32-S3-WROOM-1-N4R8 module equipped with an ESP32-S3 dual-core LX6 32-bit microprocessor, 4 MB of flash, 384 kB of ROM, and 512 kB of SRAM. This microcontroller supports both WiFi and Bluetooth for wireless communication. The 7.0-inch display itself is a capacitive touch screen with a resolution of 800×480 pixels. The display is controlled by the EK9716BD3/EK73002ACGB driver and is compatible with LVGL for additional functionality. In the case of the 3.5-inch display module, the main difference is the use of the ESP32-WROOM-32-N4 […]

ESPHome compatible “Smart Powermeter” supports up to 6 CT clamps

J.G.Aguado’s “Smart Powermeter” is an ESP32-S2 board with a 2.9-inch e-paper display designed to measure power consumption through up to six CT clamps, or Current Transformer clamps, that are each attached to one of the AC lines of a house or appliance. I used an MT87 Digital Clamp Multimeter nearly 10 years ago to easily and safely measure the power consumption of a whole house by simply clamping it on one of the cables outside and reading the results on the display. The Smart Powermeter works in the same way but can perform measurements for up to six devices, and besides seeing the results on the display the ESP32-S2 can also send the data to the cloud or local server for data gathering and analysis using ESPHome or Arduino firmware. Smart Powermeter specifications: Wireless module – ESP32-S2-MINI-1-N4R2 SoC – Espressif ESP32-S2FH4 CPU Single-core 32-bit LX7 microcontroller @ up to 240 […]

2023 Year in review – Top 10 posts, statistics, and what to expect in 2024

It’s the last day and last article of the year, so we will look at some highlights of 2023, some traffic statistics on the CNX Software website, and speculate what interesting developments may happen in 2024. Looking back at 2023 The semiconductor shortage that had happened since 2020 started to fade away in early 2023, and supplies for most electronics components and devices seem to be adequate at this time, so that was a bright spot this year, and hopefully, it will stay that way in 2024 despite geopolitical tensions. We did not have any super exciting new Arm application processors from Rockchip, Amlogic, or Allwinner announced this year, although the Amlogic S928X penta-core Cortex-A76/A55 CPU started to show up in some 8K TV boxes. The launch of the Raspberry Pi 5 SBC with a Broadcom BCM2712 quad-core Cortex-A76 processor was probably the main highlight for Arm on this side […]

LILYGO T4-S3 board combines 2.41-inch AMOLED touchscreen display with ESP32-S3R8 microcontroller

LILYGO T4-S3 is yet another ESP32-S3 board with an integrated display, but the main difference here is the 2.41-inch AMOLED touchscreen display with brighter colors than typical TFT displays. It’s actually not the first ESP32-S3 board with an AMOLED display from LILYGO as we previously covered the T-Track and T-Display-S3 AMOLED boards from the company, but the new T4-S3 has a larger 2.41-inch display with touchscreen function and an aspect ratio that may make it more suitable for a wider range of HMI applications. LILYGO T4-S3 specifications: SoC – Espressif ESP32-S3R8 CPU – Dual-core Tensilica LX7 microcontroller up to 240 MHz with vector instructions for AI acceleration Memory – 8MB PSRAM Wireless – WiFi 4 and Bluetooth 5.0 LE + Mesh connectivity Storage – 16MB SPI flash, MicroSD card socket Display – 2.41-inch RGB AMOLED touchscreen display with 600×450 resolution (QSPI controller) with 800cd/m2 brightness, 36.2 x 48.96mm active […]
