The LilyGO Blynk V1.4 (TTGO T-Call) combines an ESP32-WROVER-F with a SIM800L GSM modem, Nano-SIM slot, battery charging, and antenna connector for standalone mobile alerts. PlatformIO and the TinyGSM library initialize the IP5306 power circuit and SIM800L, then send SMS messages or issue GPRS HTTP GET requests using the carrier APN. The ESP32-WROVER-F MGN4R8 provides 4 MB of Flash and 8 MB of external PSRAM, while the board costs about 80 zł from China. SMS delivery worked instantly, and an HTTP GET request over GPRS returned headers and content through the UART console. The SIM800L supports only 2G and failed to complete HTTPS requests, making the board suitable for SMS notifications but limited for modern internet-connected projects.

LilyGO TTGO T-Call/Blynk V1.4 łączy ESP32-WROVER-F z modemem GSM/GPRS SIM800L, pozwalając wysyłać SMS-y bez Wi‑Fi przez kartę Nano SIM. TinyGSM steruje SIM800L komendami AT, a inicjalizacja przez I2C układu IP5306 i pin PWKEY zapewnia zasilanie oraz uruchomienie modemu. ESP32-WROVER-F MGN4R8 oferuje 4 MB pamięci Flash i 8 MB PSRAM, a płytkę można sprowadzić z Chin za około 80 zł. Testowy SMS dotarł natychmiast po rejestracji modemu w sieci, a zapytanie HTTP GET przez GPRS zwróciło nagłówki i treść do UART. SIM800L obsługuje wyłącznie 2G i nie uruchomił HTTPS, więc nadaje się głównie do SMS-ów, a jego przyszła użyteczność zależy od dalszego wsparcia GSM. Cały artykuł na stronie głównej elektroda.
