CYOBot v2 ESP32-S3-based open-source modular robotics platform supports up to 16 servos (Crowdfunding)

CYOBot v2 ESP32-S3 modular robotics platform

Create Your Own Bot (CYOBot) v2 is an open-source, modular robotics platform for students, educators, hobbyists, and future engineers based on the ESP32-S3 microcontroller and featuring up to 16 servo motors for complex control. The CYOBot v2 is a follow-up to the previous quadrupedal robotic platform from the same company. It adds new features such as a modular design, an upgrade to the ESP32-S3 chip, more motor channels, and an expansion block with more peripherals. It also supports integrating AI systems, such as ChatGPT, for added functionality. The CYOBot supports up to three configurations via the CYOBrain — which powers the robotics platform and controls the servo motors — and separate 3D-printed components. The CYOBot Crawler is a four-legged robot powered by eight 180-degree servo motors. The CYOBot Wheeler form factor features four 360-degree motors linked to wheels at the end of each leg and is essentially a hybrid between […]

MicroPython v1.24 release adds support for RP2350 and ESP32-C6 microcontrollers, various RISC-V improvements

Micropython v1.24 with ESP32-C6 and RP2350 support

MicroPython has become one of the most popular ways of programming microcontrollers, and the just-released MicroPython v1.24 adds support for the widely-used Raspberry Pi RP2350 and Espresif ESP32-C6 microcontrollers and a range of other changes. Those include improved RISC-V support with native code generation, an updated Zephyr v3.7.0 RTOS with threading support, unified TinyUSB bindings across ports, a portable UART IRQ API, and enhanced mpremote recursive copy. Damien George goes into more detail about the RISC-V improvements: … include an RV32IMC native code emitter, native NLR and GC register scanning implementations for 32- and 64-bit RISC-V, support for placing RV32IMC native code in .mpy files and also freezing it, and RISC-V semihosting support. Testing for RISC-V is done with the qemu and unix ports, and the support is utilised in the esp32 and rp2 ports. The Raspberry Pi RP2350 comes with both Arm Cortex-M33 and RISC-V cores, and the good […]

1.28-inch round color display features Raspberry Pi RP2350, motion sensor, GPIO headers, metal case

Waveshare has recently launched the RP2350-LCD-1.28, a Raspberry Pi RP2350-based 1.28-inch round color display module with 240×240 pixel resolution and a 65K-color IPS panel. This board also features a rechargeable Lithium battery manager, a 6-axis IMU with a 3-axis gyroscope and accelerometer, multiple GPIO pins, and a USB Type-C connector for programming and power. Additionally, it supports USB 1.1 host/device support, temperature sensor, and 24 PWM channels, all configured for flexible I/O options. These features make this device useful for IoT, wearable tech, and embedded applications. The company also provides an optional CNC metal casing that provides durability and heat dissipation for portable or rugged applications. We have previously covered similar development boards with a round display such as the RP2040-powered 0.99″ rounded display, the ESP32-S3 LCD Driver Board, the SB-Components has launched Dual Roundy, and others, but it’s the first to feature the RP2350 microcontroller. RP2350-LCD-1.28 specification: Microcontroller – Raspberry Pi […]

RP2040 FlexiBoard is a bendable Raspberry Pi Pico clone made of flexible PCB (Crowdfunding)

[Update December 22: The project was previously called FlexiPi, but Raspberry Pi considered it infringed on its trademarks, so the name was changed to RP2040 FlexiBoard instead]. RP2040 FlexiBoard is a bendable Raspberry Pi RP2040 board made of flexible PCB with the same layout as the original Raspberry Pi Pico, but featuring a USB-C port instead of a micro USB port on the official board. This follows the Flexduino flex PCB clone of the Arduino UNO made by “EDISON SCIENCE CORNER”, but the smaller design of “TOP Gadgets” RP2040 FlexiBoard may make it potentially more useful since it could be inserted into tight or round enclosures. RP2040 FlexiBoard specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ 48 MHz (overclockable to 133 MHz) with 264KB SRAM Storage – 2MB QSPI flash USB – 1x USB Type-C 1.1 port used for power and programming Expansion 2x 20-pin 2.54mm pitch header […]

Wiznet W55RP20-EVB-Pico board features W55RP20 SiP with W5500 Ethernet controller and RP2040 MCU

Wiznet has recently released the W55RP20-EVB-Pico dev board, a compact board based around the W55RP20 SiP that fuses the Raspberry Pi RP2040 MCU and the W5500 Ethernet controller into a single IC, plus a 2MB flash chip for firmware storage. Just last month we wrote about W5100S-EVB-Pico2 and W5500-EVB-Pico2 dev boards, both the boards have a newer Raspberry Pi RP2350 MCU and external Ethernet controller (W5500 or W5100S). The RP2350 offers additional security features such as One Time Programmable (OTP) memory, secure boot, and Arm TrustZone technology, making it more suitable for secure applications. The W55RP20 on the other hand integrates a W5500 Ethernet controller and the RP2040 in a single SiP which is also pin-compatible with the Raspberry Pi Pico, making it easy to use existing Pico accessories and code examples. W55RP20-EVB-Pico dev board specifications: SiP– W55RP20 microcontroller MCU – Raspberry Pi RP2040 Core– Dual Cortex M0+ cores up […]

Arduino Nicla Sense Env module features temperature, humidity, and gas sensors from Renesas

Arduino Nicla Sense Env is a new sensor module with temperature, humidity, and gas (TVOC, NO2, O3) sensing that follows the launch of the Arduino Nicla Sense ME (Motion & Environment) module over three years ago (2021). The implementation of the new module is quite different since the ME module relies on Nordic Semi nRF52832 Cortex-M4 microcontroller and Bosch SensorTech motion and environmental sensor, but the new Nicla Sense Env module is made of parts from Renesas namely the RA2E1 Cortex-M23 microcontroller, the HS4001 humidity and temperature sensor, the ZMOD4410 gas sensor for TVOC and indoor air quality, and the ZMOD4510 gas sensor for NO2, O3, and outdoor air quality. Arduino Nicla Sense Env (ABX00089) specifications: MCU – Renesas RA2E1 Arm Cortex-M23 entry-line microcontroller (not accessible or programmable by the user) CPU core – Arm Cortex-M23 core up to 48 MHz Memory – 16KB SRAM Storage – 128KB flash Sensors […]
