LILYGO® T-Solar Development Board ASR6505 Integrates SX1262LORa Module Solar Power Supply Interface

Introduction T Solar uses the new lora system chip ASR6505The ASR6505 is based on the 8 bit MCU and SX1262 SiP chip which is more cost effective than the 32 bit MCU One of the biggest features of T Solar solar powered design The solar power supply interface is reserved on the board which can be directly connected to the 5 5v 7 5v solar panel With the lithium battery the system can be operated continuously until the battery is scrapped Product Description ChipsetASR6505CPUSTM8L152LoRaSX1262Frequeccy150MHz 960MHzMaximum Power 21dBm constant RF outputRX Sensitivity 140dBmEmbedded memoryFlash 64KB SRAM 4KB EEPROM 2KBPeripherals30x configurable GPIOS 1xIC 2xUART 1xSWIM 1xSPL 3xADCRX mode Currrent10mATX mode Curent85mA 22dBm40mA 17dBm30mA 14dBmDeep Sleep Mode Current1uA Without RTC1 6uA With RTCTemperatureStorage 55 125°COperating 40 85°CHumidityStorage 5 95 Non Condensing Operating 10 95 Non Condensing Charging Current780maChargingTP4056Charging statusRed light on Green light offVoltage full stateRed light off Green light onUndervoltageRed light off Green light offBattery temperature is too high or too low stateRed light off Green light offNo battery accessRed light off Green light offBAT terminated with 10u capacitor no batteryFlashing red light T 1 4S Green light onFunctionThe solar power supply interface is reserved on the board which can be directly connected to the solar panel of 5 5 7 5V With the lithium battery the system can continue to
