Meet Dot – A stamp sized 2-wheel robot powered by a Raspberry Pi RP2040 board

Kaisar (aka Roboticbits) has developed a tiny robot based on Pironomi Tiny 2040 Raspberry Pi RP2040 development board, which he/she claims is the smallest in the world, but it might not be depending on how one measures it. Nevertheless, the Dot is a cool project with two wheels with a 3V DC motor attached to the 22.9 x 18.2 mm board, and a 70mA battery to power the mini robot. Here’s what it looks like in action. Introducing Dot.. a stamp size @Raspberry_Pi #RP2040 robot.. the smallest in the world! Makes a proper use of the @pimoroni #Tiny2040!#raspberrypi #robot #robotics #make pic.twitter.com/rnYghWY6NJ — RoboticBits (@roboticbits) November 11, 2021 Eventually, the robot should be documented on Github, but at this time we have limited information with a photo accompanying the video demo above. Tom’s Hardware got more details about the software as well, with Kaisar saying the firmware was developed with […]

Only 3 days left to get a Raspberry Pi RP2040 + ESP32 board at 80% discount (Sponsored)

There’s always a bunch of DIY electronics on Kickstarter, but right now nothing is as compelling as UDOO KEY. Built by UDOO, a multidisciplinary team that has already completed (and delivered) four highly successful Kickstarter projects, UDOO KEY is an innovative, never-before-seen combination of Raspberry Pi RP2040 and ESP32. Mind you: unlike the newest microcontroller by Arduino, UDOO KEY doesn’t simply use the ESP32 for connectivity. Instead, it features a fully programmable ESP32, offering the widest set of options in the field when it comes to Edge AI. Predictive maintenance, sound recognition, keyword recognition, gesture recognition, face recognition, object detection & classification… these are just a few of the many applications you can build, also thanks to the several programming languages and libraries supported, such as Micropython, C, C++, TensorFlow Lite and TinyML. This is not some fancy mini PC for low-budget gaming, but a platform for AI at the […]

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 […]

RAK introduces Raspberry Pi RP2040 based LoRaWAN core, more Wisblock modules

RAKwireless has just launched the RAK11310 WisBlock LPWAN Module with Raspberry Pi RP2040 MCU and LoRaWAN connectivity, as announced after launching 14 new WisBlock modules for IoT prototyping last July. The RAK11310 module was introduced as part of the “Just Track It RAK Autumn Launch 2021” event together with the smallest WisBlock Base Board so far, as well as 11 new Wisblock modules which bring the total to 47 modules. RAK11310 – Raspberry Pi RP2040, LoRaWAN connectivity RAK11310 specifications: RAK11300 WisDuo LPWAN Module MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ 133MHz with 246 kB RAM LoRa connectivity SX1262 LoRa transceiver Worldwide frequency coverage RAK11310L – EU433, CN470 RAK11310 – EU868, US915, AU915, KR920, AS923, IN865, RU865 LoRaWAN 1.0.2 protocol stack (supports Class A & C) I/O ports – UART, I2C, GPIO, USB through a “Wisconnector” Debugging – Serial Wire Debug (SWD) interface Supply Voltage – 2.0 V ~ […]

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 – […]
