It talks 5V logic, so it pairs directly with most common sensors, displays, and modules. Connect it to any FTDI breakout (3.3V or 5V) to program; the on‑board voltage regulator accepts 5–12 V on the RAW pin.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eUnlike the Uno, the Pro Mini lacks a USB‑to‑serial chip—you’ll need an external FTDI programmer for code upload. Connect DTR through a 0.1 µF capacitor to the board’s DTR pin (or toggle the reset manually). The 5V pin can source up to 400 mA, but keep current per I\/O pin below 20 mA for reliable operation.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.\u003c\/p\u003e\n\n\u003cdetails\u003e\u003csummary\u003eIs this compatible with the Arduino IDE?\u003c\/summary\u003e\u003cp\u003eYes. In the IDE, select board “Arduino Pro or Pro Mini” and processor “ATmega328P (5V, 16 MHz)”. All standard libraries and examples will compile without changes.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eDo I need a separate programmer?\u003c\/summary\u003e\u003cp\u003eYes, because the board has no USB port. An FTDI Basic breakout or any USB‑to‑serial adapter with DTR line works fine. Once programmed, it can run standalone from a battery or power supply.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eCan I use this with 3.3 V sensors?\u003c\/summary\u003e\u003cp\u003ePower the board from 5 V and use level shifters on the I²C or SPI lines. The 5 V logic will damage 3.3 V‑only peripherals without proper shifting. The on‑board Atmega328P is not 3.3 V tolerant.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
