Gotchas

3 known issues

Check your revision. Revision 1.1 is 32-bit only (Cortex-A7); revisions 1.2 and 1.3 have 64-bit Cortex-A53 cores. Revisions 1.1 and 1.2 reached end of life in October 2025.^[2]
3.3 V only. The GPIO pins are 3.3 V. Do not connect 5 V signals or components to them.^[4]
Little current per pin. Each GPIO pin can supply up to about 16 mA and all pins together about 50 mA; drive motors and other loads through a transistor or driver board.^[5]

Revisions

3 revisions

Revision 1.1: February 2015: BCM2836, four 32-bit Cortex-A7 cores. End of life on 16 October 2025.^[2]
Revision 1.2: 2016: BCM2837 with 64-bit Cortex-A53 cores, still at 900 MHz. End of life on 16 October 2025.^[2]
Revision 1.3: BCM2837B0, same footprint; the revision recommended for existing designs.^[2]

History and use today

Editorial

History

Launched in February 2015 at the same $35, the Pi 2 replaced the single ARMv6 core with four Cortex-A7s and doubled the RAM to 1 GB, which made a usable desktop possible for the first time.^[7]

Still useful for

A capable headless server for Pi-hole, a print server or home automation. Raspberry Pi still produces revision 1.3 for industrial customers.
