IoTextra modular automation boards with 4 inputs, 4 outputs work with Raspberry Pi and ESP32 MCU boards

IoTsmart IoTextra modular automation boards

Last week, we wrote about the Olimex PICO-EVB automation board equipped with four relays and four isolated inputs and designed for Raspberry Pi Pico-compatible boards. Make Things Happy does something similar, but in a modular way, with the IoTextra family of carrier boards with four inputs and four outputs for automation, and supporting a range of IoTsmart MCU boards based on Raspberry Pi RP2350, ESP32-S3, etc… There are currently six IoTextra boards shipping or in development, all measuring 56×47 mm and featuring 3750 Vrms galvanic isolation per channel. All IoTextra modules support different MCU platforms via horizontally or vertically mounted IoTsmart SoM carriers based on Waveshare RP2350 and ESP32-S3 modules, Seeed Studio XIAO boards, and others, all connected via the HOST connector. All IoTextra 8-channel modules support several software ecosystems out of the box: IoTflow framework for no-code programming of distributed MCU nodes over MQTT and Node-RED; used to build custom […]

RP2350B bells&whistles development board features on-board RP2040 debugger, HDMI, and microSD card slot

While searching Tindie for a new project, I found a new Raspberry Pi RP2350B-based development board called “Bells&Whistles,” which is interesting because it also features an onboard RP2040-based debugger running Picoprobe firmware, removing the need for a separate debug probe. Other than that, it has an HDMI output, a MicroSD card slot for storage, an optional 8 MB of PSRAM, and since it uses the Raspberry Pi RP2350B variant, it supports up to 46 GPIO pins. The board also features two USB Type-C ports, one for the RP2350B and the other for the RP2040 debugger, and is especially useful for clutter-free rapid prototyping and development workflows. RP2350B bells&whistles board specifications: SoC – Raspberry Pi RP2350B CPU Dual-core Arm Cortex-M33 @ 150 MHz with Arm TrustZone Dual-core RISC-V Hazard3 @ 150 MHz Only two cores can be used at any given time Memory – 520 KB on-chip SRAM Package – QFN-80 Memory – […]

Waveshare RP2350B-Plus-W – A Raspberry Pi Pico 2 W-sized board with 41 GPIOs, 16MB flash, USB-C port

Waveshare RP2350B-Plus-W is a development board that follows the Raspberry Pi Pico 2 W form factor, but offers 41 GPIOs thanks to the RP2350B MCU, integrates 16 MB of flash, and includes a USB-C port. So, in several ways, it’s an upgrade over the RP2350A-based official board, which offers only 26 GPIOs via two 13-pin GPIO headers, 4MB of flash, and a micro USB port. Since it’s the same size, where do the extra GPIOs come from? Answer: The company simply added 15 pads to the bottom of the board, not quite as convenient since it’s requires soldering, but it does the job. Waveshare RP2350B-Plus-W specifications: SoC – Raspberry Pi RP2350B CPU Dual-core Arm Cortex-M33 @ 150 MHz with Arm Trustzone Dual-core RISC-V Hazard3 @ 150 MHz Only two cores can be used at any given time Memory – 520 KB on-chip SRAM Package – QFN-80 Memory – Footprint […]

Flipper One – A Rockchip RK3576-powered portable Arm Linux computer and networking multi-tool

Flipper Devices has officially introduced the Flipper One open-source hardware portable Arm Linux platform and networking and Edge AI multi-tool powered by a Rockchip RK3576 octa-core Arm Cortex-A72/A53 SoC, and featuring a Raspberry Pi RP2350 for low-level control. You may think of it as a successor to the popular STM32-based Flipper Zero hardware and wireless hacking tool, but the company stresses that the Flipper One is NOT a replacement for the Flipper Zero. It is a different product with mainline Linux kernel support, no binary blobs (probably not 100% true), and open-source drivers, and operating at a different level of the networking and wireless stacks with dual Gigabit Ethernet, Wi-Fi 6E, and optional 5G or 4G LTE modem. Flipper One specifications: SoC – Rockchip RK3576 CPU 4x Cortex-A72 cores @ 2.2GHz, 4x Cortex-A53 cores @ 1.8GHz Arm Cortex-M0 MCU at 400MHz GPU – ARM Mali-G52 MC3 GPU with support for […]

Raspberry Pi RP2350 board offers NB-IoT cellular connectivity, GNSS, and Wi-Fi indoor location

Raspberry Pi RP2350 board NB-IoT cellular

Challenger+ RP2350 NB-IoT is a Feather-compatible board pairing a Raspberry Pi RP2350 microcontroller and a certified NB-IoT cellular module with built-in GNSS, suitable for long-range, low-power connectivity. It looks to be a variant of the earlier Challenger+ RP2350 WiFi6/BLE5 board that replaces an ESP32-C6 WiFi 6, BLE, and 802.15.4 module with an STMicroelectronics ST87M01 NB-IoT and GNSS module. It still offers Challenger+ RP2350 NB-IoT specifications: Microcontroller – Raspberry Pi RP2350A MCU CPU Dual-core Arm Cortex-M33 processor @ 150MHz Dual-core 32-bit RISC-V processor @ 150MHz Up to two cores can be used at a given time Memory – 520KB internal RAM 8KB OTP Storage Package – QFN-60; 7×7 mm Memory – 8MB PSRAM Storage – 8MB SPI flash Cellular connectivity Module – STMicro ST87M01-1301 LTE Cat NB2 (NB-IoT), 3GPP Release 15 Worldwide regional bands coverage – B1, B3, B5, B8, B20, and B28 Single-tone / Multi-tone / Extended TBS and 2 […]

picoZ80 – A Z80 microprocessor drop-in replacement based on Raspberry Pi RP2350B and ESP32

The picoZ80 board is a drop-in replacement for the Z80 microprocessor based on the Raspberry Pi RP2350B dual-core Cortex-M33 microcontroller and an ESP32 wireless SoC for WiFi and Bluetooth connectivity. My first computer was a ZX81 powered by a Zilog Z80 microprocessor, which was eventually phased out in 2024 after almost 50 years of production. But retro computing enthusiasts keep the platform alive, usually with softcore FPGA implementations such as MiSTer. The picoZ80 is different as it relies on the programmable I/O (PIO) state machines from the RP2350B MCU to reproduce cycle-accurate address, data, and control buses of the Z80 MPU. picoZ80 specifications: MCU – Raspberry Pi RP2350B CPU – Dual-core Arm Cortex-M33 CPU @ up to 150/300 MHz (the two RISC-V cores do not appear to be used by the project) Memory – 520KB SRAM Storage – 8KB OTP flash Package – QFN-80 Memory – 8MB PSRAM Storage 16MB flash […]

Clintech Pico – The first Raspberry Pi RP2354B board offers 48 GPIOs in Raspberry Pi Pico form factor

Designed by Clintech Ltd. in Bulgaria, the Clintech Pico Board appears to be the first development board based on the Raspberry Pi RP2354B chip with 2MB on-chip flash. It retains the same form factor as a Raspberry Pi Pico 2 but adds extra GPIOs to make use of the 48 general-purpose GPIOs provided by the RP2354B chip. Like the Raspberry Pi Pico 2, this board features 40 castellated and through holes on the sides, exposing GPIOs 0–22 and 26–28, along with 3 debug pins. Additionally, the board includes 27 extra on-board through holes that break out the remaining GPIOs (23–25 and 29–47) as well as the QSPI interface (SD0–SD3 and SCLK) for external memory. Clintech Pico specifications: SoC – Raspberry Pi RP2354B CPU Dual-core Arm Cortex-M33 @ 150 MHz with Arm Trustzone, Secure boot Dual-core 32-bit RISC-V Hazard3 @ 150 MHz (3-stage in-order pipeline; RV32IMAC with Zba, Zbb, Zbs, Zbkb, Zcb, Zcmp, and […]
