# E32-433T30D (Component) ## Description 8km UART Through Hole RF Transceiver Modules and Modems RoHS,3.3V~5.2V,-40 ~ 80C The E32-433T30D is based on the Semtech SX1278 LoRa chipset and uses LoRa spread-spectrum modulation to achieve long-distance, highly reliable wireless communication even in noisy environments. It communicates with a microcontroller via UART (serial interface), making it easy to integrate with Arduino, ESP32, STM32, and similar systems. It is commonly used for IoT telemetry, remote control systems, sensor networks, and industrial monitoring, especially where GSM/Wi-Fi is unavailable or impractical. Key Features Frequency range: 410–441 MHz (433 MHz default) RF output power: 21–30 dBm (up to 1 W high-power version) LoRa modulation: High sensitivity and strong anti-interference Communication distance: up to ~8 km (open area, ideal conditions) Interface: UART TTL serial (3.3 V logic level) Sensitivity: around -147 dBm for long-range reception Low data rate support: ~0.3 kbps to 19.2 kbps Half-duplex communication (TX/RX not simultaneous) Configurable modes: normal / wake-up / power-saving / sleep via M0 & M1 pins Compact module size with SMA antenna connector Wide operating temperature: -40 °C to +85 °C Important Notes Requires external microcontroller (MCU) for operation (not standalone). Must not leave M0 and M1 pins floating (must be defined HIGH/LOW or GND). Works best with proper 433 MHz antenna (2–5 dBi recommended). Power supply must be stable (typically 5V with sufficient current capability). For maximum range, line-of-sight + correct antenna height matters more than raw power. Applications Smart agriculture monitoring Remote sensor networks Utility meter reading (water/gas) Industrial telemetry systems Drone/robot communication links Remote control & automation systems #E32_433T30D #Ebyte #LoRa #SX1278 #WirelessModule #IoT #Telemetry #LongRangeCommunication #UART #433MHzLoRa #EmbeddedSystems ## Component Details - **Owner:** adrian95 - **Created:** 6/15/2026 - **Last Updated:** 6/15/2026 - **Visibility:** Public - **Mount:** Through Hole - **Manufacturer Part Number:** E32-433T30D - **Compliance:** Rohs - **LCSC Part Number:** C97351 - **License:** https://creativecommons.org/licenses/by/4.0/ - **Symbol Style:** parametric-v1 - **Part Type:** Module - **Datasheet URL:** https://www.cdebyte.com/pdf-down.aspx?id=1462 - **Manufacturer Name:** EBYTE - **Part Type:** Modules - **MPN:** E32-433T30D - **Mount Type:** Through Hole - **Package / Case Code:** Module - **Pin Count:** 11 - **Compliance:** Rohs ## Pins | Pin | Name | Type | |-----|------|------| | 1 | M0 | | | 2 | M1 | | | 3 | RXD | | | 4 | TXD | | | 5 | AUX | | | 6 | VCC | | | 7 | GND | | | 8 | FIXED_ORIFICE_1 | | | 9 | FIXED_ORIFICE_2 | | | 10 | FIXED_ORIFICE_3 | | | 11 | FIXED_ORIFICE_4 | | --- *Generated from [https://www.flux.ai/adrian95/e32-433t30d](https://www.flux.ai/adrian95/e32-433t30d)*
