It supplies regulated 3.3V power from a 5V input and breaks out all GPIO, UART, and control pins. Use it to prototype IoT projects without soldering directly to the module.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eInput Voltage\u003c\/td\u003e\n\u003ctd\u003e5V DC (via micro-USB or VIN pin)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutput Voltage\u003c\/td\u003e\n\u003ctd\u003e3.3V @ 800mA (AMS1117-3.3 regulator)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSupported Modules\u003c\/td\u003e\n\u003ctd\u003eESP-01, ESP-01S (ESP8266)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003ePin Pitch\u003c\/td\u003e\n\u003ctd\u003e2.54mm (breadboard-friendly DIP format)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOnboard Features\u003c\/td\u003e\n\u003ctd\u003ePower LED, 3.3V\/5V level jumper, CH_PD pull-up\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e48mm × 18mm × 10mm\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eWi-Fi sensor node with DHT11 and MQTT\u003c\/li\u003e\n  \u003cli\u003eWireless relay controller for home automation\u003c\/li\u003e\n  \u003cli\u003eSerial-to-WiFi bridge for Arduino projects\u003c\/li\u003e\n  \u003cli\u003eStandalone IoT button or notification lamp\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThe adapter accepts both ESP-01 (512 KB flash) and ESP-01S (1 MB flash) modules. It works with 5V Arduino boards for serial programming when the jumper is set to 5V, or with 3.3V USB-UART adapters in 3.3V mode. Common pairings include Arduino Uno, Raspberry Pi, and FTDI programmers.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eApply 5V to VIN or the micro-USB port; never connect 5V directly to the ESP module’s VCC pin. TX\/RX cross-connect to your programmer, and set the jumper to match your UART voltage. The CH_PD pin is pulled high by default – remove the jumper only for low-power modes.\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 Arduino Uno for programming the ESP-01?\u003c\/summary\u003e\u003cp\u003eYes, connect the adapter’s 5V pin to Uno’s 5V, GND to GND, and cross TX\/RX to Uno pins 0\/1. Set the jumper to 5V. Pull GPIO0 low before powering to enter flash mode.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eDoes the board include the ESP-01 module?\u003c\/summary\u003e\u003cp\u003eNo, this is only the breakout adapter with voltage regulator. The ESP-01 or ESP-01S module must be purchased separately.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eCan I power it directly from a 3.3V supply?\u003c\/summary\u003e\u003cp\u003eIf you have a stable 3.3V source, you can bypass the regulator by connecting directly to the 3.3V pin, but ensure your supply can handle 200mA+ peaks. The regulator is designed for 5V input.\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.
