M5Stack Fire has occupied GPIO16 / 17 to connect with the PSRAM by default, it's conflict with TXD / RXD (GPIO16, GPIO17) of SIM800L module. Therefore, when using the SIM800L module with the M5Stack Fire, you might have to cut the TXD and RXD from SIM800L module and wire fly to another set of UART pin
Include
- 1x M5Stack SIM800L Module
Applications
- Nitrogen dioxide alarm
- Automatic Web Spider SMS-notifier
- Remote meter reading system
