Giveaway Week – Maker Pi Pico board

If you have not played with Raspberry Pi Pico board, here’s an opportunity, as the third prize of our giveaway week is the Maker Pi Pico board fitted with the Raspberry Pi RP2040 MCU board, and providing easy access to I/Os with headers and Grove connector, plus a buzzer, an audio jack, and a MicroSD card socket for people needing storage. I reviewed the Maker Pi Pico board with CircuitPython, and it was more convenient than the bare Raspberry Pi Pico thanks to the reset button and an LED is assigned for each I/O. You could also add an ESP-01 module for WiFi connectivity since there’s an 8-pin header for that purpose. The CNXSoft signature on the back of the board clearly brings infinite value to the board. It’s just like an NFT, except it’s real ;). If you don’t think so, you could always use some alcohol to wipe […]

$15 Raspberry Pi Zero 2 W launched with quad-core CPU, 512MB RAM

Raspberry Pi Zero 2 W is the first quad-core SBC from the Raspberry Pi Foundation with the Raspberry Pi Zero form factor. Based on the RP3A0 system-in-package (SiP) comprised of a Broadcom BCM2710A1 quad-core Cortex-A53 processor and 512MB LPDDR2, the new Pi Zero W 2 board offers the exact same interfaces as its predecessor. This includes a MicroSD card socket, a mini HDMI port, two micro USB ports, a MIPI CSI-2 camera connector, as well as an unpopulated 40-pin GPIO header. The wireless module appears to have changed but still offers WiFi 4 and Bluetooth 4.x BLE, and it’s using the same VideoCore IV GPU to handle 3D graphics and video encoding and decoding up to 1080p30. Raspberry Pi Zero 2 W specifications: SiP – Raspberry Pi RP3A0 system-in-package with: SoC – Broadcom BCM2710A1 quad-core Arm Cortex-A53 @ 1GHz (overclockable to 1.2 GHz) with VideoCore IV CPU supporting OpenGL ES […]

LEGO Technic meets Raspberry Pi with the Build HAT

Raspberry Pi Build HAT with LEGO Technic

A new official Raspberry Pi expansion board is introduced today. The Built HAT provides four connectors for LEGO Technic motors and sensors from the SPIKE Portfolio, as well as an 8V DC jack to power both the Raspberry Pi and LEGO motors, sensors, LED matrix, and more. Designed in collaboration with LEGO Education, the Build HAT features the Raspberry Pi RP2040 dual-core ARM Cortex M0+ MCU for I/O control, and will enable more complex models benefiting from more powerful Broadcom BCM2xxx processors, as well as a Python library for easy programming. Build HAT key features and specifications: MCU – Raspberry Pi RP2040 microcontroller for low-level control of LEGO Technic devices 4x LPF2 connectors for LEGO Technic motors and sensors included in the SPIKE Portfolio 40-pin GPIO header for connection to Raspberry Pi 4 Model B, 3B+, 3B, 3A+, or Pi Zero family (Raspberry Pi 400 not supported) Misc – 2x […]

Iono RP – An industrial PLC with a Raspberry Pi RP2040 MCU

Raspberry Pi RP2040 MCU has been used in many boards, but I think I had seen the dual-core MCU in a PLC, or even any industrial products just yet. Sfera Labs Iono RP is a compact I/O module (PLC) with a Raspberry Pi RP2040 microcontroller that’s programmable in C/C++ and MicroPython, or even the Arduino IDE. The DIN-Rail mountable, RP2040 based industrial PLC offers digital and analog input and output lines, power relays, and an RS-485 interface, supports power input from 12V-24V with all signals accessible through terminal blocks. Sfera Labs can also provide some optional options such as an RTC or an earthquake sensor module. Iono RP PLC specifications: MCU – Raspberry Pi RP2040 dual-core Arm Cortex-M0+ @ 133MHz with 264kB on-chip SRAM Storage – 16MB SPI flash, optional microSD card slot Communication interface – standard RS-485 interface with electrostatic discharge protection Inputs/Outputs via terminal blocks 4x power relay […]

UDOO KEY ESP32 & RP2040 board launched for $4 (Crowdfunding)

UDOO is known for its x86 boards that embed an Arduino compatible MCU, but the UDOO KEY is different, as it does without an Intel or AMD processor, and instead, combines Raspberry Pi RP2040 microcontroller with Espressif ESP32 WiFi & Bluetooth WiSoC. As we noted in the past combining Raspberry Pi Pico/RP2040 with ESP32 does not make a lot of sense in most cases, but here’s the UDOO KEY will be offered for just $4 for the first 1,000 units, so they’ll basically throw the ESP32 for free since it’s the same price as one Raspberry Pi Pico, before eventually selling the device for $20. UDOO KEY specifications: MCU- Raspberry Pi RP2040 dual-core Arm Cortex-M0+ microcontroller @ 133 MHz with 264KB of on-chip SRAM Storage – 8MB QSPI Flash for RP2040 Wireless module – ESP32-WROVER-E with ESP32-D0WD-V3 dual-core WiFi + Bluetooth SoC, 16MB SPI flash, and 8MB PSRAM Sensor – […]

$10 LILYGO T-Display RP2040 board integrates a 1.14-inch color display

As its name implies, LILYGO T-Display RP2040 is a Raspberry Pi RP2040 based development board that comes with a display, and more exactly a 1.14-inch color display with 240×135 resolution and based on ST7789V SPI display driver. The T-Display RP2040 board joins other Rasberry Pi RP2040 boards with integrated displays like Arducam Pico4ML, but does so at a much lower price with LILYGO selling the board for just $9.98 on Aliexpress. LilyGO T-Display RP2040 specifications: Microcontroller – Raspberry Pi RP2040 dual-core Cortex-M0+ MCU with 264 KB of embedded SRAM Storage – 4MB SPI flash Display – 1.14-inch full-color IPS LCD Display (ST7789V SPI controller) with 240 x 135 resolution Expansion – 15-pin + 12-pin expansion headers with 14x GPIOs, 6x PWMs, up to 2x UART, up to 2x I2C, up to 2x SPI, 2x programmable high-speed I/O, 5V, 3.3V, Vbat, and GND Misc – Boot & enable buttons, 2x user […]

Challenger RP2040 WiFi board marries ESP8285 with Raspberry Pi RP2040

We’ve already seen Raspberry Pi RP2040 getting WiFi connectivity with boards like Pico Wireless Pack, Wio RP2040 mini, and Arduino Nano RP2040 Connect in ways that do not always make technical and commercial sense as in many cases, the WiFi microcontroller (e.g. ESP32) is more powerful than the Raspberry Pi microcontroller. But Invector Labs’ Challenger RP2040 WiFi board does make more sense, as the company combines Raspberry Pi RP2040 dual-core Cortex-M0+ MCU with an entry-level ESP8285 WiFi microcontroller, and also offers LiPo battery support, all that in the Adafruit Feather form factor. Challenger RP2040 WiFi board specifications: Main microcontroller – Raspberry Pi RP2040 dual-core Cortex-M0+ MCU @ 133MHz with 264KB SRAM Storage – 8MB flash Network microcontroller – Espressif ESP8285 2.4GHz WiFi 4 SoC with 1MB on-chip flash pre-flashed with Espressif’s AT command interpreter, connected to the main MCU over UART at up to 921600 bps; I/Os via Adafruit Feather […]
