Built for Technicians. Designed for the Field.

Crescent Technical courses are not for spectators. They are for the technician who wants to understand what is happening inside the system — not just follow a checklist someone else wrote.

Whether you are just getting started in electronics, moving into RF and wireless communications, or ready to deploy your first IoT sensor network, the CT series gives you a structured path from fundamentals to field-ready skills — with hands-on lab exercises at every step.

If you have ever opened a piece of equipment and wanted to understand what you were looking at, you are in the right place.

The Crescent Technical Course Series

The CT series is a structured curriculum covering Electronics, RF, and IoT from the ground up. Each course builds on the one before it. Complete the series and you have the integrated knowledge base of a well-rounded field technician.

Why Crescent Technical

Three differentiators

One Curriculum. Three Disciplines.

Electronics, RF, and IoT do not exist in separate boxes in the real world. A technician deploying a LoRaWAN sensor network needs electronics fundamentals, RF propagation knowledge, and IoT protocol skills simultaneously. The CT series teaches them as an integrated body of knowledge — not three unrelated courses.

Built Around Real Hardware.

Every CT-401 lab exercise runs on hardware you can buy today and use on a real deployment tomorrow. The ESP32 V3 LoRa board, DHT22 and BME280 sensors, Raspberry Pi gateway stack, TTN, InfluxDB, and Grafana — the same tools working IoT technicians use every day. No simulations. No toy examples.

What You Need to Get Started

Prerequisites and hardware

What You Need to Get Started with CT-401

Prerequisites:

CT-401 is designed for anyone with a basic electronics background. You should be comfortable with Ohm’s Law, able to use a multimeter, and familiar with basic circuit concepts before beginning. If you need to build that foundation first, watch for the CT-101 through CT-105 Foundation Series is available now.

Hardware Required:

• ESP32 V3 LoRa development board — 2 to 3 recommended

• IoT sensors — DHT22, BME280, soil moisture, DS18B20 temperature probe

• Raspberry Pi 4 for the local gateway and monitoring stack

• Breadboard, jumper wires, resistors, and basic components

• A complete parts list with purchase links is provided in the course materials

• Estimated hardware cost: $150 to $250 depending on what you already have

 Software:

• All software used in CT-401 is free and open source

• Arduino IDE, Mosquitto MQTT, InfluxDB, Grafana, Node-RED, and The Things Network

• No paid subscriptions required to complete the course
