Which Development Board Fits Your Needs?

PocketBeagle versus Raspberry Pi Zero

By: Megan Tung

Due to the small size of these boards, they are ideal for portable projects such as robots, custom gaming devices, or controlling a quadcopter. The PocketBeagle can fit into a mini Altoids tin and the Raspberry Pi Zero is slightly larger, both being smaller than a credit card.

Processor
and

Memory
  • Octavo Systems OSD3358-SM SiP (system-in-package)
  • 1GHz Sitara AM3358 ARM Cortex-A8 SoC
  • Memory – 512 MB of DDR3 800 MHz RAM and a 4 KB EEPROM.
  • 3D-ready PowerVR SGX530 graphics
  • NEON floating-point accelerator
  • 64 KB dedicated RAM and 64 KB shared L3 RAM
  • Two 32-bit 200 MHz PRUs (programmable real-time units): great for low-latency and real-time applications
  • Broadcom BCM2835 SoC (system-on-chip)
  • 1GHz ARM11, single core 32-bit processor
  • Memory – 512 MB of LPDDR2 SDRAM
  • Dual core Videocore IV GPU, which give it the capabilities of full HD displays at 60 FPS
Requirements to Getting Started

 

Size
1960 sq. mm (56mm x 35mm x 5mm) 1950 sq. mm (65mm x 30mm x 5mm)
Number of
Pin Headers
72-pin headers
  • Pro: More pin headers means more space for analog inputs, digital IOs & other peripherals
  • Con: Many BeagleBoard capes will not work or will require manipulation

40-pin headers

  • Pro: HATs used with the Raspberry Pi 2 and 3 work with the Raspberry Pi Zero since both have 40-pin headers
  • Con: Less pin headers than PocketBeagle
Mounting
