 If you are new to mesh networking, Mestastic is one of the easier ones to grasp. If you are looking to DIY your own Arduino-esque off-grid texting device with a 3D printed case, this is the network most hobbyists are doing that on.

+//**Important Note:** Meshtastic devices are calibrated to specific frequencies! The frequency you use will depend on if you are using it **encrypted** on the low-power ISM bands (915MHz in America, 433MHz/868MHz in Europe) or **unencrypted** on the high-power amateur radio bands (70cm and 33cm). **Make sure you have the right device for your region & use case, or you will not be able to communicate with the people around you!**//

 The simplest kind of Meshtastic node is a glorified repeater, since by default all nodes rebroadcast packets from nearby nodes. These types of nodes you can basically just configure and place somewhere, and it will start repeating whatever it picks up.
-These types of nodes can be built all sorts of ways with common off-the-shelf components. Some of them come with cool features like being able to control them from a phone or PC via Bluetooth or USB. If you want a node that is already partially or fully assembled, try one of these:

+=== Heltec T114 & LoRa 32 ===
+[{{ :radio:meshnology.jpeg?200|Heltec boards are often sold in kits like this. Pictured: Meshnology N32.}}]
+The Heltec Automation's [[https://heltec.org/project/mesh-node-t114/|T114]] is a popular Meshtastic-compatible LoRa device. It is controlled via Bluetooth and comes in a variety of form factors - including bare-bones circuit boards for which you can 3D print your own case. If you want a T114 that's ready to go, it is recommended you get one of these [[https://www.amazon.com/Heltec-Meshtastic-T114-Crabiner-Bluetooth/dp/B0F3X3WNJP|compact kits]] with the 800mah battery, or the larger [[https://www.amazon.com/Mesh-Node-T114-3000mAh-nRF52840/dp/B0FCM5RT66/|Meshnology N36]] kit with the 3000mah battery. The [[https://muzi.works/products/h2t-complete-device-heltec-t114-with-gps-running-meshtastic|Muzi Works H2T]] is another popular T114-based option.
+The **LoRa 32** is Heltec's more advanced board, offering wifi support amongst other things not available in the T114. Again you can get these as bare boards, but one of Meshnology's [[https://www.amazon.com/Heltec-32-Development-Meshtastic-Compatible/dp/B0FJXW21CC|N32]] or [[https://www.amazon.com/Meshnology-ESP32-LoRa-V3-Development/dp/B0F4DN2M2T/|N33]] kits is a quicker way to get started. The [[https://muzi.works/products/h1-complete-device-with-upgraded-whip-antenna-heltec-v3-running-meshtastic|Muzi Works H1]] is another preassembled offering. All of these kits come with 3000mah batteries.

You control it on your smartphone with Bluetooth, but there are other more arcane ways //(UART, SPI, TWI, PDM, 12S, QSPI, 802.15.4)// to tap into it as well. Comes with 850mah battery and GPS module.

+If you want batteries larger than 2000mah, don't be dismayed: You can 3D print all sorts of [[https://www.printables.com/search/models?q=lilygo+tdeck|fancy cases]] that accommodate different battery sizes. The GPS  module isn't necessary, but you will want it if you are going to be using the T-Deck for off-grid hiking emergencies.
