FAQs
Frequently asked questions
Can’t find your answer? Ask the team directly.
What kinds of projects does Sai Agro Tel take on?
Embedded electronic products and controllers for agricultural, industrial and domestic applications: hardware and PCB design, firmware, IoT connectivity, enclosures, testing and production support. You can engage us for one stage or for the complete product.
Can you start from just an idea?
Yes. Many projects start as an idea or a rough requirement. We begin by clarifying the requirement and proposing an architecture before design work starts, and can take the idea through proof-of-concept to a finished product.
Which microcontrollers and platforms do you work with?
Firmware in C and C++ on ARM Cortex-M3, M4 and M7 (including NXP LPC1788), Espressif ESP32, PIC, AVR and other microcontrollers; an RTOS (Keil RTX or FreeRTOS), the ESP-IDF framework on ESP32, or embedded Linux where the product needs them; and application software on Android, Windows and the web.
How can we engage you?
As a proof-of-concept, a fixed-scope project or long-term product engineering — whichever fits the stage your product is at.
Can I buy Driptel or Gardentel online?
Not through an online checkout. Send a product enquiry with your location, application and quantity, and the team will reply with availability, pricing and installation guidance.
