Prime BLE1 Bluetooth Module Review: Specs, Limits, Fit

Prime BLE1 Bluetooth Module review covers Prime industrial BLE use, Gadgeteer fit, specs, sourcing and support limits.

Prime BLE1 Bluetooth Module is best read as a Mountaineer Prime industrial BLE reference for Gadgeteer NETMF prototyping, not a current retail wireless option. No public datasheet for Prime BLE1 details exists as of Nov 2026, while the related Mountaineer Ethernet Mainboard uses a 168 MHz STM32F407 with 192 KB RAM, according to the .NET Micro Framework e-shop accessed Nov 2026.

What is the Prime BLE1 Bluetooth Module for?

Prime BLE1 serves industrial prototyping that needs short-range wireless on Mountaineer Prime reference designs introduced in 2013, according to Mountaineer Group history accessed Nov 2026. Mountaineer Prime was created to speed industrial NETMF solutions beyond basic mainboards, according to the same history accessed Nov 2026. The testing method used here weights documented specs and support status over assumed radio performance.

How does Prime BLE1 fit Gadgeteer systems?

Prime BLE1 fits Gadgeteer systems through 10-pin sockets carrying UART, I2C, SPI and digital I/O, according to Mountaineer Group platform description accessed Nov 2026. A Mountaineer Eth mainboard with an Oberon BLE Gadgeteer module already had a community enclosure published 15 May 2014, according to Thingiverse dated 15 May 2014. That pairing shows the practical path: mainboard handles C# logic on Visual Studio tooling, BLE module handles short links, with the Ethernet mainboard for wired gateways and the USB mainboard for compact nodes.

What are Prime BLE1 specs and limits?

Prime BLE1 has no public radio datasheet as of Nov 2026, while siblings measure 57 x 42 mm and 57 x 32 mm, according to Mountaineer datasheets accessed Nov 2026. The sibling Ethernet design integrates 168 MHz STM32F407 control, 1 MB on-chip Flash, 8 MB external Flash and 8 Gadgeteer sockets, according to the .NET Micro Framework e-shop accessed Nov 2026. Both Mountaineer mainboards are RoHS compliant and lead-free for 0-70C operation, according to Mountaineer datasheets accessed Nov 2026.

Board	MCU / memory	Size / interfaces
Mountaineer Ethernet Mainboard	168 MHz STM32F407, 192 KB RAM, 1 MB Flash plus 8 MB external Flash	57 x 42 mm, 8 sockets plus USB and Ethernet
Mountaineer USB Mainboard	168 MHz STM32F407, 192 KB RAM, 1 MB Flash plus 8 MB external Flash	57 x 32 mm, compact USB-powered layout
Prime BLE1 Bluetooth Module	No public datasheet as of Nov 2026	BLE function for Prime reference designs, details unavailable

Bluetooth range itself spans more than a kilometer down to less than a meter on the 2.4 GHz ISM band from 2400 to 2483.5 MHz, according to Bluetooth SIG range page accessed Nov 2026. Early BLE 4.0 hardware ran at 1 Mbps raw radio rate with 150us gaps and 80-bit acknowledgements, according to Memfault guide dated 24 Sep 2019. NETMF runs lean at about one percent of full framework size, with 48 KB RAM usable and 192 KB luxurious, according to Mountaineer Group FAQ accessed Nov 2026.

When should you still use Prime BLE1?

Prime BLE1 makes sense only for maintaining legacy NETMF prototypes because support ended in Dec 2017, according to Mountaineer Group news dated Dec 2017. The last active line was Mountaineer 4.3.1 Beta 3 released 09-Apr-2014 after Beta 2 on 31-Mar-2014, according to Mountaineer Group news dated 2014. Listed Ethernet stock was 6 units at EUR 81.07 incl VAT with a selling-off note, according to the .NET Micro Framework e-shop accessed Nov 2026, so new builds should plan a modern BLE migration.

Prime BLE1 FAQ

What is the Prime BLE1 Bluetooth Module best for?

Prime BLE1 Bluetooth Module is best for keeping a Mountaineer Prime prototype running where short BLE links supplement Gadgeteer mainboards. It is not a basis for new products because firmware support ended and no datasheet or supply chain exists.

Does the Prime BLE1 Bluetooth Module have public specs?

Prime BLE1 Bluetooth Module has no public pin, power or radio datasheet as of Nov 2026. Sibling Mountaineer mainboard specs and general BLE characteristics can bound expectations, but exact Prime BLE1 limits remain unavailable.

Can the Prime BLE1 Bluetooth Module be sourced today?

Prime BLE1 Bluetooth Module cannot be sourced as a supported new part through documented channels. Related Mountaineer Ethernet stock showed sell-off status and support ended in Dec 2017, so reuse, remake or migration is the realistic path.
