SX1276 LoRa AS32 TTL-1W-C 433MHz Long Range Transceiver Module (Original)

Description

SX1276 LoRa AS32 TTL-1W-C 433MHz Long Range Transceiver Module (Original) SX1276 LoRa AS32 TTL-1W-C is a 1W industrial wireless data transceiver with high stability, operates at 433MHz. The module adopts SX1278 incorporating the LORA spread spectrum modem and efficient loop error correction algorithm, which greatly improves the anti-interference ability and stability. The AS32 TTL-1W-C has four operation modes and can be switched freely in the runtime. In power saving mode, the current consumption is extremely low, ideal for applications of ultra-low current consumption. Features Point-to-point transmission, transparent transmission, and wake-on-radio functionality. Efficient cycle interleaving error correction code (up to 64-bit correction). Receiving sensitivity up to -130dBm; communication range up to 3000 meters. Sleep current consumption as low as 1.5μA. Ultra-low receiving current consumption. Automatic relay and continuous transmission capability. Built-in data encryption. RSSI and voltage are readable. Multiple exception handling mechanisms ensure long-term stable operation. Maximum transmission power approximately 30dBm (around 1W ). Operation Modes: MD0 = 0, MD1 = 0: General operation mode. MD0 = 0, MD1 = 1: Power-saving mode. MD0 = 1, MD1 = 0: Wake-up mode. MD0 = 1, MD1 = 1: Sleep mode. Frequency and Channels: Frequency range: 410–441MHz. Default operating frequency: 433MHz (license-free ISM band). Power Supply range: 2.5V to 5.5VDC . Specifications Parameter name Description Min Typical value Max Units Supply voltage If the power supply voltage is less than 3.6V, the output power will decline, but it has little influence on the received power. 2.5 5.5 V Transmitting current Max transmission power is about 30dBm (about 1W). 520 mA Receiving current General working mode (MD0 = 0, MD1 = 0). 17 mA Power saving mode (MD0 = 0, MD1 = 1). 30 mA Wake-up mode (MD0 = 1, MD1 = 0). 17 mA Sleep mode (MD0 = 1, MD1 = 1). Sleep current Current measured in sleep mode (MD0 = 1, MD1 = 1). 1.5 μA Working frequency 410–441MHz, 1MHz stepping, 32 channels, factory default 433MHz. 410 433 441 MHz Transmit power 30 dBm Airspeed 6 levels adjustable (0.3kbps, 1.2kbps, 2.4kbps, 4.8kbps, 9.6kbps, 19.2kbps). 0.3k 2.4k 19.2k bps Receiving sensitivity The receiving sensitivity has nothing to do with the serial port rate or delay time. -130 dBm Operation temperature Industrial product. -40 +85 ℃ Operation humidity Relative humidity, no condensation. 10% 90% Storage temperature -40 +125 ℃ PINOUT Pin Number Pin Name Pin Orientation Pin Usage 1 MD0 Input (weak pull-up) Works with MD1 to select one of four operation modes. 2 MD1 Input (weak pull-up) Works with MD0 to select one of four operation modes. 3 RXD Input TTL UART input, connects to external TXD pin; configurable as open-drain or pull-up input. 4 TXD Output TTL UART output, connects to external RXD pin; configurable as open-drain or push-pull output. 5 AUX Output Indicates module status and wakes external MCU; outputs low during self-test; configurable output. 6 VCC Power Supply Power supply input, 2.5–5.5V (below 3.6V lowers output power, minimal reception impact). 7 GND Ground Ground reference connected to power supply ground.
