RP2350 Tiny and Tiny XL boards clone Solder Party’s RP2350 stamp layouts at nearly half the price

RP2350 Tiny and Tiny XL boards

While searching Aliexpress, I stumbled upon the RP2350 Tiny and Tiny XL, both of which are RP2350-based low-cost stamp-size development boards that look exactly like the Solder Party’s “RP2350 Stamp” modules, but are available at nearly half the price. Both modules feature the Raspberry Pi RP2350 dual-core Arm Cortex-M33 microcontroller and an integrated LiPo charging circuitry. The RP2350 Tiny offers 30x GPIOs, while the larger RP2350 Tiny XL breaks out 48x GPIOs, adds PSRAM, and includes SWD/UART JST connectors. Key interfaces include USB host/device, UART, SPI, I²C, PWM, ADC, and PIO state machines, along with Secure Boot and Arm TrustZone. These features make this board suitable for rapid prototyping and testing with CircuitPython support. RP2350 Tiny and Tiny XL specifications: Microcontroller RP2350 Tiny – Raspberry Pi RP2350A MCU, QFN-60; 7×7 mm RP2350 Tiny XL – Raspberry Pi RP2350B MCU,QFN-80; 10×10 mm Memory – 520KB internal RAM, 8KB OTP storage Storage – 16MB […]

Compex “JustWiFi⁷™” driverless, Ethernet-connected Wi-Fi 7 module delivers up to 10 Gbps throughput (Sponsored)

Compex JustWiFi7 vs WiFi7 dual band dual concurrent module

Compex Systems (Compex) is redefining how wireless is integrated into modern embedded and industrial systems with the launch of JustWiFi⁷™, a one-of-a-kind, driverless, tri-band concurrent Wi-Fi 7 module that connects through Ethernet protocols. Designed to eliminate the complexity of traditional wireless integration, JustWiFi⁷™ makes high-performance Wi-Fi deployment faster, simpler, and smarter. Rethinking Wi-Fi Integration: No Drivers. No Hassle. JustWiFi⁷™ Most of the Wi-Fi modules today rely on PCIe, SDIO, or USB interfaces and are controlled through drivers. Developers will need to deal with the drivers’ compatibility with the host platform, particularly its OS and kernel version. The drivers for Wi-Fi 7 are particularly complex due to the standard’s advanced features. Many open-sourced drivers and sometimes the host CPU are not able to deliver the full capabilities of the Wi-Fi 7 chipset. These complications often unnecessarily slow down and add to the development time and effort. Engineered for speed, simplicity, and […]

RAK3112 WisDuo LoRa + WiFi + BLE module targets Edge AI and Meshtastic UI

RAK3112 WisDuo module

RAKwireless “RAK3112 WisDuo Module for Edge AI with LoRa” combines an ESP32-S3 WiFi and BLE SoC with a Semtech SX1262 LoRa transceiver for Edge AI applications and Meshtastic user interfaces. The 3-in-1 LoRa + WiFi  + BLE module is an update to the ESP32-based RAK11200 WisDuo LoRa module, which has limitations in terms of computing power and memory. Those became apparent in more demanding applications such as Edge AI or complex mesh networks. With 16MB of flash and 8MB of PSRAM and a more powerful ESP32-S3 microcontroller, the RAK3112 WisDuo module overcomes those limitations for camera and audio processing, as well as mesh networks like Meshtastic. It also offers a more powerful alternative to the pin-compatible RAK11160 STM32 + ESP32-C2 module that’s better suited for battery-powered sensors. RAKwireless RAK3112 specifications: Main MCU – Espressif Systems ESP32-S3 CPU – Xtensa 32-bit LX7 dual-core CPU @ 240 MHz with vector instructions, AI […]

Core1121 sub-GHz, S-Band, and 2.4GHz LoRa module features through holes and castellated edges

Core1121 LF HF Dual Band LoRa Module

The Waveshare Core1121 is a compact, multi-band LoRa module based on the Semtech LR1121 transceiver with support for Sub-GHz (150–960MHz), S-band (1.9–2.1GHz), and 2.4GHz ISM bands, and exposing GPIOs through both through and castellated holes. Key features include support for LoRa, (G)FSK, and LR-FHSS modulation schemes, AES-128 encryption, and compatibility with the SX126X/SX127X series for easy migration. We just noted Seeed Studio’s Wio-LR1121 last week with a very similar, yet more compact design with only castellated holes, and before that, the LR1121 was used in the MuRata Type-2GT module and a LILYGO module as an option for the T-Eth Elite board.

JC ESP32P4 M3 DEV ESP32 P4 evolution board

While searching Aliexpress for new products, I found out about the JC-ESP32P4-M3-DEV from the Maker Go AliExpress store, another ESP32-P4 development board with features very similar to the  ESP32-P4-Function-EV-Board or the Wireless Tag WT99P4C5-S1 board, but built around the GUITION JC-ESP32P4-M3-C6 module, which combines ESP32-P4 and ESP32-C6 into a single package instead of having separate chips or modules on most other designs. Features include 32MB of PSRAM and 16MB of flash on the GUITION module, a microSD card slot for storage, a built-in microphone, speaker output via the ES8311 audio codec, and an audio amplifier. The board also offers a 10/100Mbps Ethernet RJ45 port, an RS-485 terminal block, a GPIO header, and expansion connectors for both the ESP32-P4 and ESP32-C6 chips. Additionally, there are three USB ports: two USB-C and one USB-A for power, data, and debugging, along with a few buttons and LEDs. JC-ESP32P4-M3-DEV evolution board specifications: Core module […]
