Solar power manager module supports 6V-24V input range, battery charging, MPTT function, and outputs 5V/3A

Raspberry Pi 4 solar panel

Waveshare Solar Power Manager Module (D) is a compact power module for solar panels with support for 6V to 24V input, MPTT (Maximum Power Point Tracking), and battery charging. It outputs 5V up to 3A via a USB-C port or terminal block and should be suitable for a range of projects. A few weeks ago, we wrote about the FireBeetle 2 ESP32-C6 IoT development board with DFRobot highlighting support for solar charging of lithium batteries thanks the the CN3165 chip. But with a range of just 4.5 to 6V for solar panel input and a lack of support for MPTT, several readers were unimpressed by the solution. The Waveshare Solar Power Manager Module (D) recently popped up in my news feed, and I thought it might be worth a look. Waveshare Solar Power Manager Module (D) specifications: Solar panel input 6V to 24V via DC jack or 2-pole screw terminal […]

Waveshare PCIe to M.2 adapter for Raspberry Pi 5 will only cost you $8.99

Waveshare PCIe To M.2 Adapter for Raspberry Pi 5

The Waveshare PCIe To M.2 adapter is an inexpensive PCIe to M.2 HAT+ module for the Raspberry Pi 5 designed for PCIe Gen2 and Gen3 SSDs. It is compatible with standard SSD sizes of 2230/2242 and features status indicator LEDs, a power monitoring chip, an EEPROM, and a cooling fan vent to keep temperatures in control during heavy use. It’s not the first Raspberry Pi 5 adapter taking NVMe SSDs (or AI accelerator), as we previously explored the PineBerry Pi’s HatDrive, suitable for 2230, 2242, and 2280 SSDs up to PCIe Gen3 speeds and the Pimoroni NVMe Base with a different design and compatible with 2230, 2242, 2260, and 2280 drives up to PCIe Gen3 speeds. A few days ago, we already covered Waveshare’s PoE HAT(F), which shares a similar form factor with Waveshare PCIe To M.2 Adapter and uses the new HAT+ standard to provide 24W of power to […]

Raspberry Pi 5 gets a PoE HAT+ kit that doubles as a cooling solution

Raspberry Pi 5 PoE HAT+

Waveshare PoE HAT(F) is an 802.3af/at-compliant 24W Power-over-Ethernet (PoE) HAT+ board designed for the Raspberry Pi 5 that also cools the SBC with its embedded fan, a heatsink, and two thermal pads. The Chinese company has beaten Raspberry Pi to it as the UK company is working on releasing the L-shaped 25W “PoE+ HAT(+) for Raspberry Pi 5” a little later. The existing official Raspberry Pi PoE+ HAT delivers up to 25.5 Watts which would be enough to power the Pi 5, but since the PoE header has been moved to another location, it’s not compatible anymore, so new solutions are needed such as the Waveshare PoE HAT(F). Waveshare PoE HAT(F) specifications: Supported SBC – Raspberry Pi 5 only Connected via 40-pin Raspberry Pi GPIO header and 4-pin PoE header PoE (Power Over Ethernet) IEEE 802.3af/at-compliant Input voltage – 37V-57V DC input Output 2-pin header – 12V/2A max GPIO header […]

$44 5G M.2 to Ethernet and USB “converter” takes M.2 5G PCIe modules

5G M.2 to Ethernet and USB converter

Waveshare “5G M.2 to Gigabit Ethernet converter, 5G M.2 to USB3 converter” is a single device designed to easily and cheaply add 5G connectivity to a LAN through a gigabit Ethernet port or to a specific host like a PC or a Raspberry Pi SBC through a USB 3.1 Type-C port. The 5G M.2 to Ethernet and USB converter is flexible as by default it does not ship with a 5G module, but features an M.2 Key-B socket for 5G 3042 or 3052 modules allowing it to meet the requirements of a specific location. 5G M.2 to Ethernet and USB converter key features and specifications: Cellular M.2 Key B socket for 3042/3052 5G modules from SIMCom (SIM82XX), Quectel (RM5XX), and Fibocom (FM160XX) Onboard standard SIM card slot 4x 5G omnidirectional high-gain antennas Ethernet – Gigabit Ethernet RJ45 port using RealTek RTL8125 controller USB – USB 3.1 Type-C port for connection […]

Tiny Raspberry Pi RP2040 module connects to USB-C + buttons board via FPC connector

Raspberry Pi RP2040 module with FPC USB-C board

Waveshare RP2040-Tiny is another tiny Raspberry Pi RP2040 module that joins others like Pimoroni Tiny 2040, DFRobot Beetle RP2020, or Solder Party RP2040 Stamp, but with a twist as the solderable module features an FPC connector in order to optionally connect a separate board with a USB-C port as well as Boot and Reset buttons. This design enables the convenience of having a USB-C port for power and programming, plus the Reset and Boot buttons during firmware development, and developers can only keep the tiny and ultrathin module when integrating it into a project or product. Alternatively, there may be designs that benefit from having the USB-C port located further away from the main module with all I/Os, and it can also facilitate troubleshooting when the product is already integrated into a product. Waveshare RP2040-Tiny specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ up to 133Mhz with 264kB […]
