Yes. We only source Arduino, Raspberry Pi, Espressif (ESP32/ESP8266), Adafruit and SparkFun products through authorised distributors. Every board ships with manufacturer serial numbers and warranty cards. We do not stock unofficial clones unless explicitly labelled as such.

Yes — Arduino, Raspberry Pi, ESP32 and similar microcontrollers are completely legal to import, sell and use in India. ioToys imports through authorised channels with proper customs paperwork and BIS compliance where applicable.

ioToys is headquartered in Bengaluru, Karnataka, India. We have been operating since 2018.

Arduino Uno R3 uses the ATmega328P (8-bit, 16 MHz, 32 KB flash). The newer Uno R4 (Minima/WiFi) uses the Renesas RA4M1 (32-bit Cortex-M4, 48 MHz, 256 KB flash) and adds optional Wi-Fi/Bluetooth on the R4 WiFi variant. R4 is backwards compatible with most R3 sketches and shields.

ESP32 has dual-core 240 MHz, 4 MB+ flash, integrated Bluetooth, more GPIOs and stronger Wi-Fi — best for serious IoT, BLE and battery projects. ESP8266 is cheaper (~Rs.150 less), single-core 80 MHz and adequate for simple Wi-Fi sensors and switches. New projects in 2026 should default to ESP32.

Raspberry Pi 5 has a 2.4 GHz quad-core Cortex-A76 CPU (~2-3x faster than Pi 4), faster I/O via the new RP1 chip, native PCIe 2.0 and a real-time clock with battery slot. Pi 4 is still excellent value if you need 4 GB or 8 GB RAM at lower cost. Pi 5 is the right choice for desktop replacement, AI/ML at the edge and high-performance IoT gateways.

Arduino Uno R3 is the safest starting point — millions of tutorials exist, the boards are forgiving of wiring mistakes and shields are widely available. Pair it with a sensor + module starter kit and our blog tutorials.

Start with our Arduino Uno R3 + Sensor Bundle (~Rs.1,499) or the ESP32 Smart Home Starter Kit (~Rs.2,499). Both include the board, breadboard, jumpers, common sensors (DHT11, ultrasonic, PIR), LEDs and a project booklet.
