Raspberry Pi Zero 2 W board gets Raspberry Pi CM3 adapter

Raspberry Pi Zero 2 W CM3 adapter

A couple of months ago, we wrote about the Raspberry Pi Compute Module 3E (CM3E) equipped with the Raspberry Pi RP3A0 SiP found in the Raspberry Pi Zero 2 W board. It looks like an OEM product from Raspberry Pi trading, and as such is close to impossible to purchase. But if somehow, you’d like to have the guts of the Pi Zero 2 W into CM3 module form factor, Waveshare has designed the Zero-to-CM3 adapter for the Raspberry Pi Zero 2 W that should be compatible with most carrier boards designed for Raspberry Pi CM3 or CM3+. As you can see, it is also using pogo pins to connect to the test points on the Raspberry Pi Zero 2 W board in order to route the USB, USB OTG, and SD card signals, so it will not work on older Pi Zero boards since the test points are in […]

RM500U-CN Raspberry Pi 5G HAT kit sells for under $200… for the Chinese market

Waveshare has introduced a new Raspberry Pi 5G HAT kit with a Quectel RM500U-CN 5G module, four antennas, and other accessories that sells for under $200, Raspberry Pi SBC not included. On the face of it, it looks like an incredible deal, considering we’ve previously covered two other 5G development kits for the Raspberry Pi, namely Waveshare SIM8200EA-M2 HAT with a Snapdragon X55 5G modem and Sixfab “Raspberry Pi 5G Development Kit” that sold for about $400 to $600. What’s the trick? It’s designed for the Chinese market. RM500U-CN Raspberry Pi 5G HAT kit content: Waveshare Raspberry Pi M.2 TO 4G/5G HAT Quectel RM500U-CN 5G M.2 module 4x antennas plus SMA protective caps and IPEX adapter cables USB 3.0 male to male cable 1x USB 3.0 adapter and 1x USB 2.0 adapter 40-pin header 5V/3A USB Type-C power adapter Screws pack We can find more details about the RM500U-CN module […]

CM4-IO-POE-4G-Box – A Raspberry Pi Compute Module 4 box for industrial IoT applications

While the Raspberry Pi Compute Module 4 is basically unobtanium, companies keep introducing products based on the Arm system-on-module, and Waveshare CM4-IO-POE-4G-Box is a complete system designed for industrial IoT applications with CAN Bus, RS232 and RS485 interfaces, Ethernet with PoE support, plus optional support for 2G to 5G cellular connectivity. The CM4-IO-POE-4G-Box is based on the “Compute Module 4 PoE 4G” carrier board which itself appears to be an update to the company’s earlier “Compute Module PoE 4G” carrier board for the Raspberry Pi CM3 module. CM4-IO-POE-4G-Box / Compute Module 4 PoE 4GB board specifications: Support SoM – All variants of Raspberry Pi Compute Module 4 Storage – MicroSD card socket used for Raspberry Pi Compute Module 4 Lite (without eMMC) Display 2x HDMI ports up to 4Kp30 (I suppose even 4Kp60) 2x 15-pin MIPI DSI connectors + openings in the enclosure for flat cables Camera – 2x internal […]

Waveshare CM4-Duino – An Arduino compatible carrier board for Raspberry Pi CM4

Waveshare CM4-Duino is a carrier board for Raspberry Pi Compute Module 4 (CM4) that follows Arduino UNO R3 form factor while offering HDMI output, a MIPI CSI camera interface, a USB interface, and even an M.2 M Key socket for expansion. This allows the board to reuse most Arduino shields while offering the flexibility of a more powerful Arm Linux platform that can further be expanded with an NVMe SSD or a wireless module through the included M.2 socket. Waveshare CM4-Duino specifications: Support SoM – All variants of Raspberry Pi Compute Module 4 Storage MicroSD card socket for Compute Module 4 Lite (without eMMC) variants Optional NVMe SSD via M.2 socket Video Output – HDMI up to 4Kp30 (not sure why 4Kp60 would not be supported) Camera I/F – 1x MIPI CSI-2 connector USB – 1x USB 2.0 Type-A header, 1x USB Type-C for power and programming Expansion M.2 M […]

Add four PCIe x1 slots to Raspberry Pi CM4 IO with Waveshare PCIe-Packet-Switch-4P board

The 1-lane PCIe Gen 2 interface in Broadcom BCM2711 processor is exposed in Raspberry Pi CM4, and most carrier boards are exploiting the interface including the official Raspberry Pi Compute Module IO carrier board. But if you ever wanted to connect multiple PCIe cards to the CM4 IO board, Waveshare has got you covered with the PCIe-Packet-Switch-4P that provides four PCIe x1 slots through an ASMedia ASM1184e PCIe switch.   PCIe-Packet-Switch-4P expansion board specifications: Compatible with Raspberry Pi Compute module 4 IO board 4x PCIe Gen 2 x1 expansion slots, compatible with PCIe Gen 1 x1 ASM1184e PCIe switch taking 1x PCIe x1 Gen2 upstream port to 4x PCIe x1 Gen2 downstream ports; no driver required, plug and play Power Supply 12V via PCIe interface or 12V via DC jack (or even 5V see warnings below) Dimensions – 82 x 39 mm There are some interesting warnings in the Chinese […]

USB add-on boards leverage Raspberry Pi Zero test pads, USB Gadget mode

I’ve just come across a few USB boards that take advantage of the Raspberry Pi Zero (W) test pads to add one or more USB Type-A ports to the board without soldering. The first one is “Catda Raspberry Pi zero WH USB expansion board” which I found on Banggood for $9.99. It’s a kit that ships with a USB Zero plug expansion module, an acrylic “isolation protection cover”, an acrylic transparent light diffraction protection cover plus M2.5 screws and nuts for mounting it to the Raspberry Pi Zero WH board, but it should work any Raspberry Pi Zero including the new Raspberry Pi Zero 2 W board since it relies on pogo pin to connect the four test pads for USB data and power, and those are in the same position for all Pi Zero boards. You can then plug it into a laptop or computer to power the board […]

Quad GPIO Expander for Raspberry Pi Pico adds battery, display module, sensors, etc…

People are normally using MCU boards for their low cost, low-power consumption, low price and/or real-time ability. The Raspberry Pi Pico is no exception, but if you don’t care about using a large board, Waveshare created a 177 x 62 mm “expander” board for the Raspberry Pi Pico that can take four modules. The company’s Quad GPIO Expander board includes a set of female headers for RPi Pico, and four sets of 2×20 male headers for extra modules that bring support for 14500 batteries, OLED displays, RTC, relays, and other compatible modules. The expansion board also has a Micro USB port for power, and to leave the Micro USB OTG port on the Raspberry Pi Pico for other purposes. Each header pin is clearly labeled, which could be useful if using some of the pins with jumper wires instead of modules. Waveshare has hundreds of different modules and somehow decided […]

Raspberry Pi CM3 “Industrial IoT” baseboard features PoE, 4G LTE modem, and isolated I/Os

The Raspberry Pi Computer Module 4 (CM4) may have been introduced in October, but that does not mean people have stopped all development on Raspberry Pi CM3/CM3+ hardware, and Waveshare has just launched a carrier board for the module with PoE support and a 4G LTE modem namely Simcom SIM7600G-H module with 3G and 2G fallback. The board also offers Ethernet and WiFi connectivity, HDMI and MIPI CSI/DSI video interfaces, multiple USB ports, as well as isolated CAN bus, RS485, RS232, and other I/Os for industrial applications. Compute Module PoE 4G board specifications: Storage – MicroSD card slot for Raspberry Pi CM3 Lite / CM3+ Lite modules Video Output – HDMI 2.0 port, MIPI DSI connector compatible with the official Raspberry Pi display Audio – 3.5mm stereo audio jack, 4-pin speaker connector for 8Ω/5W speaker Camera I/F – 2x independent MIPI CSI ports Connectivity 10/100M Ethernet RJ45 port with PoE […]
