3 | 3 | `Shepherd Nova` is the public instance of the Shepherd Testbed - |
4 | | -a public testbed for rigorous experiments under repeatable energy-harvesting conditions. |
5 | | -In the second half of 2023 a semi-open instance of the Shepherd testbed went live. |
6 | | -Public access is scheduled to launch during the MobiSys 2025. |

| 11 | +## What does the testbed offer? |
9 | 12 |
|
10 | 13 | - [10+ observer-nodes](/content/deployment.md) for distributed operation |
11 | | -- [nRF52-Targets](https://github.com/nes-lab/shepherd-targets/) with additional MSP430 that can be used as FRAM |
| 14 | +- [nRF52-Targets](https://github.com/nes-lab/shepherd-targets/) with additional MSP430 that can be used as FRAM for checkpointing |
12 | 15 | - consistently replicate real-world spatio-temporal energy availability across multiple experiments |
13 | 16 | - replay of [energy environments](/content/environments.md) in combination with |
14 | 17 | - an energy harvesting-component called [virtual power source](/content/virtual_source.md) to supply power to the targets (optional) |
15 | 18 | - record power traces at a rate of 100 kHz with separate values for current & voltage (optional) |
16 | 19 | - timestamping with sub 1us accuracy across the testbed |
17 | 20 | - recording of target-GPIO with up to 1 MHz and 9 / 12 channels (optional) |
18 | 21 | - decoding of UART at configurable baud rate (optional) |
19 | | -- patching of node-ID in target-firmware (optional) |
| 22 | +- patching of node-ID in `ELF` target-firmware (optional) |
20 | 23 | - embedded logs, including an extensive warning-system that supervises & diagnoses every critical element during operation |
21 | 24 | - tooling in and around the system (batteries included) |
