A new GPIO Screw Terminal Hat has been introduces for Raspberry Pi SBCs, namely Raspberry Pi 4 Model B, Raspberry Pi 3 Model B/B+, Raspberry Pi Zero (W). Raspberry Pi 2 Model B, and Raspberry Pi Model B+. A range of GPIO is now exposed as screw terminal, for fast connection to the mainboard.
This is a very beautiful screw terminal expansion version, which is expanded for the pins of the Raspberry Pi. It is convenient for everyone to connect when doing electronic experiments. There is the pinout information of the GPIO pin on the top of the terminal and on the side. The status information of the pin is displayed. When the GPIO pin is operated and effective in the terminal, the LED matrix on the right side of the terminal will display the status of the GPIO pin, and some distinctions are made in the color selection of the LED lights.

ModBerry 500 CM4 an ultimate solution for IoT monitoring
TECHBASE’s ModBerry industrial computer series has received an update to Compute Module 4 and is available for orders. TECHBASE is leading manufacturer of Industrial Raspberry Pi and Industrial Compute Module solutions. ModBerry 500 series is fully compatible with all releases of Compute Module from Rasbperry Pi foundation.
Main features of updated device are:
- up to 4x faster eMMC Flash with up to 32GB storage
- up to 2x faster performance of CPU appllications than previous CM3 version
- up to 8x more RAM (8GB LPDDR4-3200)
- 1Gbit Ethernet interface
- PCI 2.0 card support for NVMe SSD drive (via M.2)
- two PCIe support for wireless modem solutions, i.e. LTE/5G modems
Raspberry Pi Compute Module 4 world premiere
Few days ago, Raspberry Foundation announced new member of its family, a Rasbperry Pi Compute Module 4. It’s quite obvious, even from the first look, that the new module is very different from its predecessors. Main difference is a new form factor, leaving DDR2 SODIMM in the past.
The same 64-bit quad-core BCM2711 application processor as in Raspberry Pi 4B, the Compute Module 4 brings higher performance: faster CPU cores, better multimedia, more interfacing capabilities, and, for the first time, a choice of RAM densities and a wireless Wi-Fi and Bluetooth connectivity options.
Compute Module 4 comes in 32 variants. Lite, as always, offers no eMMC memory, a and standard versions come with up to 8GB RAM, 32 eMMC Flash and wireless modem.
New features of Compute Module 4
- 1.5GHz quad-core 64-bit ARM Cortex-A72 CPU as in Raspberry Pi 4 version B
- 1GB, 2GB, 4GB or 8GB LPDDR4-3200 SDRAM
- 8GB, 16GB or 32GB eMMC Flash storage for Standard version, Lite version without eMMC
- Optional 2.4GHz and 5GHz IEEE 802.11b/g/n/ac wireless LAN and Bluetooth 5.0
- Single-lane PCI Express 2.0 interface
- Gigabit Ethernet PHY with IEEE 1588 support
- Dual HDMI interfaces, at resolutions up to 4K
- 28 GPIO pins, with up to 6 × UART, 6 × I2C and 5 × SPI
