ESPi Ethernet & info display board comes with ESP32-S3 module or Raspberry Pi Pico W board (Crowdfunding)

ESPi board ESP32 S3 Ethernet Display Joystick

SB Components’ ESPi is a WiFi-enabled Ethernet board with a 1.14-inch information color display either coming with an ESP32-S3 WiFi and Bluetooth module or designed as a carrier board for the Raspberry Pi Pico W board. I have no idea who needs this, but the ESPi board looks cute and can be used as a 10/100Mbps Ethernet to WiFi (or BLE) gateway with a small TFT display, and there’s also a small joystick on the board to control a potential menu or user interface rendered in the display. ESPi board specifications: Module/Board (one or the other) ESP32-S3-WROOM-1 module with ESP32-S3 dual-core LX7 microprocessor @ up to 240 MHz with Vector extension for machine learning, up to 16MB flash, up to 8MB PSRAM, WiFi 4, and Bluetooth 5 with LE/Mesh Raspberry Pi Pico W board with Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ 133 Mhz with 264KB RAM, 8MB SPI flash, […]

Wokwi – An Arduino, Raspberry Pi Pico, and ESP32 board simulator

WOKWI Arduino Raspberry Pi Pico ESP32 simulator

Wokwi is an online simulator for Arduino, Raspberry Pi Pico, and ESP32 boards, or even your own custom microcontroller board designed to learn programming without the actual hardware. My girlfriend’s daughter has just attended a free 5-day online course about AI, IoT, ESP32, MicroPython, and more organized by King Mongkut’s Institute of Technology Ladkrabang (KMITL) and IMAKE Innovation, a STEM education company in Thailand. I was told they had some homework for ESP32 as part of the course, so I asked her whether she wanted an ESP32 board. But she said no need. So then I asked how to program the ESP32 without the board, or do they have a simulator? And indeed I was sent the screenshot below along with a blurry video showing the LED display updated as the program runs in the web browser. Considering ESP32 boards are so cheap and external modules or a breadboard are […]

Cytron CM4 Maker Board review – Part 2: NVMe SSD, RTC, Buzzer, Grove modules, ChatGPT…

We’ve already checked out Cytron’s CM4 Maker Board kit with a Raspberry Pi CM4 system-on-module and booted the system with the included 32GB “MAKERDISK” Class 10 microSD card preloaded Raspberry Pi OS in the first part of the review. For the second part of the CM4 Maker review, I’ve mostly used the 128GB NVMe SSD provided by the company and played with other features of the board including the RTC, the buzzer, some Seeed Studio grove modules, and even got help from ChatGPT for one of the Python programs I used. Booting Cytron CM4 Maker Board with the “MAKERDISK” NVMe SSD I connected several Grove modules with GPIO and I2C interfaces, a Raspberry Pi Camera Module 3, an Ethernet cable, two RF dongles for a wireless keyboard and mouse, an HDMI cable to a monitor, and finally inserted the provided 5V/3.5A USB-C power adapter. The MAKERDISK SSD comes with Raspberry […]
