Product Introduction
Product Overview
8BIT-LW01H is a LoRaWan module designed and developed by Xi’an Babbit
Technology Co., Ltd., which is used for ultra-long-distance spread spectrum
communication. The chip ASR6601 is a general-purpose LPWAN wireless
communication SoC that integrates an RF transceiver, modem, and a 32-bit RISC
MCU. The MCU uses an ARM core and operates at up to 48MHz. The 8BIT-LW01H
module supports LoRa modulation.
The 8BIT-LW01H module provides ultra-long-range and ultra-low ower
communication for LPW AN applications and can be widely used in many
application scenarios such as smart metering, smart logistics, smart
buildings, smart cities, and smart agriculture.
Functional features of the module:
- Stamp hole encapsulation
- Frequency bands: 902MHz-138MHz
- The operating voltage is 3.3V, and the theoretical maximum transmit power is +22dBm
- High sensitivity: -136dBm @125Kz SF12
- Spread spectrum factor: SF5/SF6/SF7/SF8/SF9/SF10/SF11/SF12
- 128KB FLASH,16KB SRAM
- Supports LoRa modulation
- Power consumption is as low as 1.3uA in sleep mode

Module application guidance circuit
Explanation
- The customer’s antenna should be located at the corner or edge of the main circuit board and connected to the RF-ANT pin of the module through a microstrip line. The impedance matching of the microstrip line must be controlled at 50 ohms. The circuit needs to reserve a π matching circuit to optimize RF performance. The default R1 resistance is 0 ohms, and C1 and C2 are not soldered.
- The power pins of the module need to be designed with 100nF and 10uF capacitors, as well as TVS components.
- The IO port of the module needs to be connected in series with a resistor to suppress interference. If the IO port level of the control chip is not 3.3V, then the level-matching problem needs to be considered.
