Welcome to the About Raspberry pi Page

To the left are pictures of 4 Raspberry pi boards. Amateur Radio Operators are succesfully using all 3 of these pi boards in their hotspot projects.

Picture of the Raspberry pi zero immediately to the left. The Raspberry pi zero is a very basic board, but many are using it and achieving excellent results. It is the lowest performance board of the 4 shown in the pictures to the left. Here's a breakdown of the full specs on the Raspberry Pi Zero W: 1GHz, Single-core CPU. 512MB RAM. Mini HDMI and USB On-The-Go ports.




Picture of the Raspberry pi 3A+ immediately to the left. The 3A+ is the latest release of the Raspberrypi series. The pi 3A+ uses the Broadcom BCM2837B0, Cortex-A53 64-bit SoC 1.4 GHz Processor. Has 512MB of LPDDR2 SDRAM. The 3A+ offers 2.4 GHz and 5 GHz IEE 802.11.b/g/n/ac wireless LAN, Bluetooth 4.2/BLE. Has the same Extended 40-pin GPIO header as the other pi Products.







Picture of the Raspberry pi 3B immediately to the left. The Raspberry pi 3B is a a mid performance board, the 3B and 3B+ are the boards of choice for most building hotspots. It offers great performance. Here's a breakdown of the full specs on the Raspberry 3B: SoC: Broadcom BCM2837. CPU: 4x ARM Cortex-A53, 1.2GHz. GPU: Broadcom VideoCore IV. RAM: 1GB LPDDR2 (900 MHz) Networking: 10/100 Ethernet, 2.4GHz 802.11n wireless. Bluetooth: Bluetooth 4.1 Classic, Bluetooth Low Energy. Storage: microSD. GPIO: 40-pin header, populated.




Picture of the Raspberry pi 3B+ immediately to the left. The Raspberry pi 3B+ is the highest performance board of the Raspberry pi series, and some are using it and achieving excellent results. It is the highest performance board of the 4 shown in the pictures to the left. Here's a breakdown of the full specs on the Raspberry Pi 3B+:  1.4GHz ARMv8, Four-core CPU. VideoCore IV graphics and a multimedia GPU. 1GB of LPDDR2 SDRAM RAM. Full size HDMI and 4 Full Size Type A USB Receptacles. Networking: 2.4 GHz and 5 GHz IEE 802.11.b/g/n/ac wireless LAN, Bluetooth 4.2/BLE.



Picture of a Radio Hat Board immediately to the left. There are a myriad of Radio Hat Boards available. It is a personal preference as to which Hat is selected. They vary as to which Bands are covered. Careful selection will ensure the Hat covers the desired Band. Bands covered by most are the 144 Mhz, 440 Mhz and 900 Mhz. Some only cover 440 Mhz. Some also cover the 220 Mhz Band.
