Built around the ASR6502 System-in-Package, it combines an ARM Cortex-M0+ microcontroller running at 48MHz with Semtech's SX1262 LoRa transceiver, delivering +21dBm TX power and -134dBm receive sensitivity across global ISM bands (433MHz, 470-510MHz, 863-870MHz, and 902-928MHz).\n\nThe V2 revision upgrades from the ASR6501 to the ASR6502 with improved RF impedance matching and 1dB better receive sensitivity compared to the original. With just 3.5uA deep sleep current, it is exceptionally well-suited for battery-powered and solar-powered remote sensor deployments. The module supports LoRaWAN 1.0.2 Class A/B/C operation and includes AT command transparent transmission for simplified integration.\n\nThe CubeCell Arduino framework provides full Arduino IDE and PlatformIO compatibility, making it accessible for rapid prototyping. The 1.27mm stamp-hole edge design enables reliable SMT assembly while exposing 8 GPIO pins, SPI, I2C, UART, a 12-bit ADC channel, and SWD debug interface. Community projects range from soil moisture monitors and compost temperature trackers to letterbox notification sensors, validating its strengths in agricultural IoT, environmental monitoring, and smart home sensing applications. ## Where to Buy - [Heltec Official](https://openhardware.directory/r?to=https%3A%2F%2Fheltec.org%2Fproject%2Fhtcc-am01-v2%2F&ref=openhardware.directory&product=heltec-cubecell-am01-v2&source=md-export) — 9.90 - [Alibaba](https://openhardware.directory/r?to=https%3A%2F%2Fwww.alibaba.com%2Fproduct-detail%2FHeltec-iot-CubeCell-Module-HTCC-AM01_1600286671803.html&ref=openhardware.directory&product=heltec-cubecell-am01-v2&source=md-export) — 9.00 ## Resources - [product](https://openhardware.directory/r?to=https%3A%2F%2Fheltec.org%2Fproject%2Fhtcc-am01-v2%2F&ref=openhardware.directory&product=heltec-cubecell-am01-v2&source=md-export) - [github](https://openhardware.directory/r?to=https%3A%2F%2Fgithub.com%2FHelTecAutomation%2FCubeCell-Arduino&ref=openhardware.directory&product=heltec-cubecell-am01-v2&source=md-export) - [wiki](https://openhardware.directory/r?to=https%3A%2F%2Fdocs.heltec.org%2Fen%2Fnode%2Fasr650x%2Fhtcc_am01%2Findex.html&ref=openhardware.directory&product=heltec-cubecell-am01-v2&source=md-export) - [datasheet](https://openhardware.directory/r?to=https%3A%2F%2Fresource.heltec.cn%2Fdownload%2FCubeCell%2FHTCC-AM01_V2%2FHTCC-AM01_V2%28Rev1.1%29.pdf&ref=openhardware.directory&product=heltec-cubecell-am01-v2&source=md-export) - [schematics](https://openhardware.directory/r?to=https%3A%2F%2Fresource.heltec.cn%2Fdownload%2FCubeCell%2FHTCC-AM01_V2%2FHTCC-AM01_V2_Schematic_Diagram.pdf&ref=openhardware.directory&product=heltec-cubecell-am01-v2&source=md-export) ## Tags `lora`, `lorawan`, `iot`, `low-power`, `asr6502`, `sx1262`, `cubecell`, `heltec`, `module` ## Images ![CubeCell AM01 Module V2 (HTCC-AM01)](https://nbg1.your-objectstorage.com/openhardware-directory/entities/heltec-cubecell-am01-v2/c74a1ba817bd.png) ![CubeCell AM01 Module V2 (HTCC-AM01)](https://nbg1.your-objectstorage.com/openhardware-directory/entities/heltec-cubecell-am01-v2/186223971b85.png) ![CubeCell AM01 Module V2 (HTCC-AM01)](https://nbg1.your-objectstorage.com/openhardware-directory/entities/heltec-cubecell-am01-v2/2c0ba9a87d33.png) --- [View full device page](https://openhardware.directory/devices/heltec-cubecell-am01-v2)
