Home / Parts / Compare Put up to four catalogue parts side by side. BananaBoard shows exact structured values, their conditions and sources—and keeps unknown or inapplicable fields explicit.
Choose 2–4 parts Values come directly from the source-cited catalogue. Unknown is kept unknown; this tool does not infer compatibility.

Electrical Core Dual ARM Cortex-M0+ (RP2040) Source Max Clock Flash 32 KB Source ~0.5KB is used by the bootloader.
2 MB Source Onboard QSPI flash (W25Q16JV or equivalent).
SRAM Logic Voltage Onboard Regulator Yes Source Onboard buck-boost SMPS generates 3.3V from VSYS.
Operating Voltage 7 – 12 V Source Recommended input range on VIN; the board also runs directly from 5V USB.
1.8 – 5.5 V Source VSYS input range — the onboard regulator produces the 3.3V rail from this.
Interface GPIO Count 22 Source 14 digital (D0-D13) + 8 analog (A0-A7); A6/A7 are analog-input only.
26 Source GPIO broken out on the 40-pin header (the RP2040 chip has 30 total; GP23/24/25/29 are used internally and not exposed).
ADC Channels 3 Source GP26/27/28 on the header; a 4th internal ADC channel reads the onboard temperature sensor and isn't exposed as a pin.
ADC Resolution Wi-Fi No Source Use the Pico W for WiFi — different board, different part.
Bluetooth Interfaces i2c, spi, uart Source Also has 8 PIO state machines for bit-banging custom protocols, not represented by this field.
Physical USB Connector Varies by vendor The official original Nano used Mini-USB; most Nanos sold today are clones that ship with Micro-USB instead — check your specific board.
Package Length Width Weight Mounting tht Source Sold with unpopulated through-hole pads by default; the board also has castellated edges so it can instead be reflow-soldered as an SMD module onto a carrier PCB.
Header Format breadboard-friendly Source Explicitly designed to straddle a standard breadboard.
